How do bootleg software and movie releases end up in general circulation on the internet?

Once the release groups have stripped the copyright protection from software, or encoded leaked movies, they are packaged, quality assessed and then uploaded to 'topsites'. These are lightning fast, highly exclusive FTP servers with an abundance of hard drive space. Topsites are shared by a number of affiliated release groups, usually in the region of twenty. When new releases hit the topsites, couriers take hold of the reigns by distributing the releases to other topsites all over the world.

While they're at it, some of these couriers, who are sometimes referred to as 'dumpers', transfer copies of the latest releases to 'dump sites'. These represent the preceding rung of the ladder - like topsites they are private, fast and FXP enabled FTP servers.

From these dump sites, FXP groups and IRC channel operators distribute the data further. FXP groups scan for publicly accessible, anonymous FTP servers and then transfer the releases from the dump sites to these FTP servers by means of FXP (File Exchange Protocol). These free for all FTP servers are known as pubs. Once filled they are posted in public or private FXP forums so as to allow the members to share their contents.

The releases multiply exponentially as more and more people gain access to them. Once this process is set in motion it is virtually unstoppable - data transfers snowball until the releases have been spread to every corner of the globe via a variety of peer to peer applications.

MP3: music for the digital age

No internet harvesting training course would be complete without a bit of information on finding and downloading free music, so here's my attempt at guiding you to do just that. First a little bit of background information to give you a rough idea of what I'm talking about. When people use the phrase "free music on the internet" they are referring to MP3 files. MP3 is a fairly recent development in the computer music industry.

Music tracks are encoded from CDs and converted to compressed files with an MP3 extension. These can then be transferred back and forth across the internet, can be stored on your hard drive in the same manner as any other file format and require nothing more than Window's default media player to play them back (although Winamp makes a much better job of it). There's nothing new or revolutionary about this - we have been doing it for years now. The only difference is the transition between file formats.

Until recently, music was encoded in wave format (with a .wav extension) and a typical music track would occupy somewhere between 40 and 50 megabytes of hard disk space, which was obviously very inconvenient for transfer via the internet. So the critical change that the MP3 format brought about was a drastic reduction in file size, allowing much easier distribution over the internet, even for 56k modem users. To give you an example, a typical MP3 file will vary in size between 3 and 4 megabytes (depending on the 'bitrate' or quality in layman's terms) and provides near CD quality sound.

Locating and downloading MP3 tracks

So now the history lesson is over I'll get on with explaining how and where to find your next music fix. Many of the techniques that apply to other kinds of file foraging will also be useful for finding MP3s, so if you've already read my introductory lessons you'll be well equipped to begin your search.

The most dedicated MP3 aficionados tend to bypass more traditional transfer methods, instead opting for much more user friendly file-sharing clients. Of course, before the recent court ruling which imposed new restrictions on the exchange of copyright protected material, Napster ruled the MP3 sharing roost. Those days are, however, long gone. Not that this is likely to spell the end for the sharing of digital music; Napster was just the tip of the iceberg, the granddaddy which gave birth to the modern file sharing client if you like.

While Shaun Fanning deserves full credit for putting the wheels of the free (or at least reasonably priced) music machine in motion, we shouldn't be bowing our heads in silence to commemorate the fallen hero, but saluting his contribution whilst looking ahead at a much more sophisticated range of replacements.

The sheer number of alternative clients is astounding, yet many of them are plagued with problems, the most detrimental ones concerning difficulties in connecting to the networks used to transfer files and store user's file databases. We have all witnessed how vulnerable these centralised networks are to legal action - this is precisely why there has been a marked propensity of late to develop de-centralised systems whereby no single server exists that can be shut down in order to drive the network off-line.

Piolet utilizes such a system and is rapidly shaping up to be the number one Napster replacement. While the current version is still in its infancy, it has the potential to be more popular than Napster ever was and not least because the two programs are so similar. Piolet, as Napster once was, is built on the foundation of simplicity and ease of use, and this is precisely what will attract exiled ex-Napster users by the droves.

To help illustrate the point let me draw your attention to the fact that Piolet requires no installation whatsoever. You download a single file from the program's home page and you're ready to rock; the download is the whole client. Once it has finished downloading you can place it in any folder you like and simply double click on it to get started; the client automatically 'plugs' you into the community where you can begin searching for music tracks.

Also proudly riding the simplicity bandwagon is the anonymity factor. The program doesn't require you to register so you don't have to waste time thinking of a unique username or trying to remember your password before logging on as you would with many of Piolet's competitors. This means you are totally anonymous, a fact which the lack of any integrated spyware will also attest to.

OK, I take it you've had time to download and start the client by now... and if not, why not? Getting this baby up and running is absolute child's play. While it will run perfectly well 'out-of-the-box', it's always a good idea to set your preferences the first time you run any new application. To do this click on the 'config' tab. If your primary language isn't English, now's the time to tell Piolet.

With that precursor taken care of it would be advantageous to inform the client of what sort of connection you are employing to allow other users to estimate how long it is going to take them to download files from your hard drive, and also how long it is going to take you to download files from them.

From within the same 'connection' tab it is also possible to choose a nick name by which people can identify you. This isn't essential and doesn't have to be unique to you, although it's a simple way to introduce yourself to the people you are exchanging files with - it's just a matter of common courtesy really.

With that taken care of, it's time to switch to the 'uploads' tab. This is the area which allows you to select which folders will be made available to other Piolet users. To do this, click on the 'add' button and then use the integrated explorer to choose the folders where your MP3 files are stored. Note that it is advisable to have at least a few files available so that you can begin trading; you're not going to be too popular if you turn up to the party without a bottle!

Below the 'add' folders option are two input boxes. These allow you to restrict the number of files other users can grab from your computer simultaneously. Obviously if you're lumbered with a feeble dial-up modem it would be a good idea to keep this number fairly low (I would suggest setting this to just one or two simultaneous connections, and the maximum number of connections per user to one). If on the other hand you've been blessed with the use of a T1 or faster connection then throw caution to the wind and be as generous as humanly possible.

The final option which requires tweaking is the folder where you wish to store your downloads. You've guessed it; the menu which allows you to do this can be found under the 'downloads' tab, so click on that now and select a drive with plenty of free space available. The other options can be left alone to use the default settings unless you run into difficulties later.

While you were taking care of the formalities, the Blubmeister (it used to be known as Blubster) was busy logging you into the network. You will now have reached the point where you will be allowed to search through and download the collections of other users, in exchange for allowing other users to have access to your files.

So what do you have to do to embark upon your MP3 foraging quest? The first step is to click on the 'search' tab where you will be prompted to fill in a few details relating to your query. You don't have to be a genius to work out what to put in the 'artist' and 'title' boxes so I won't spell it out for you here. Note that these are the only fields which have to be completed to conduct a search.

See, I told you this was child's play didn't I. Having pressed the search button, the results will quickly be presented in the lower window from which it will be possible to reorganise the tracks to narrow down your search. For instance, if you click on the title at the top of the 'bitrate' column, the files will be rearranged according to the sound quality of the tracks.

A useful rule of thumb is not to download anything with a bitrate of less than 128 kb/s. This is the middle of the road setting, which offers a nicely balanced sound quality to file size ratio. Choosing anything less than this figure will result in finding music with a smaller file size, but a lower sound quality, and the converse is true for anything with a higher bitrate. If you've got plenty of hard drive space and a fast connection aim for the highest bitrate tracks available.

Now if you click on 'velocity', the tracks will once again be re-organised, this time according to the connection speed of the user serving the files whilst still taking into account the bitrate value which we specified previously. This is an example of a secondary categorisation. Avoid modem users like the plague, instead set your sights on at least a cable connection, but obviously the faster the connection the better.

Clearly the more people who are connected to a single user's computer at any one time, the smaller the bandwidth limit is for each person. This is why it is wise to download from someone with as fast a connection as possible. Modem users clearly have far less bandwidth available to begin with, which is why such users are best avoided.

'Ping rate', the final option, is much more variable than the preceding two and so will have a lesser effect on your downloads. The ping rate is the length of time it takes for a message to travel from your computer to a remote computer and back again, a bit like a digital boomerang if you like. Note that this figure is not the same as a user's static connection speed (56k for example) because it is dependent on a multitude of other factors. These can include the number of simultaneous connections the user is currently accepting, the number of concurrent downloads he or she is making, and whatever else the user happens to be doing online whilst using the Piolet client.

Although it is advisable to choose the download location with the highest ping rate, since any of these factors can vary at a moment's notice, meddling with this setting will not necessarily yield salient improvements in transfer speeds. So if the range of ping rates offered are very similar don't spend too much time worrying about which download location to choose unless you find that your connections are crawling along at a snail's pace.

Once the track list has been neatly rearranged according to filename, file size, connection speed and so on, downloading is simply a matter of double clicking on whatever takes your fancy. In the same way, other people can download your files without you having to do anything. If you are searching for a particular album, a good tip is to go and find the CD cover for it first (refer to the links at the bottom of the CD burning tutorial for some excellent sources). This way you don't have to wrack your brain trying to recall the names of every track that is on the album because the back cover will contain an official track listing. Armed with a scanned CD inlay you will know exactly which tracks to look for, and in what order they should be burnt to a CD-R if you plan to produce an audio CD later.

The Piolet client also includes an MP3 player and an integrated chat program, which allows you to communicate with your fellow 'Blubsies' via private messages. In short, it is a virtual music community where you can meet new friends, exchange files, run and dance naked in the fields and live happily ever after in a perfect state of melodious bliss! It really is a musical utopia - I've gone too far again haven't I? You really should stop me before I get carried away you know. Trust me though, it's damn good... and if you don't believe me check out some of the independent reviews at Zero Paid. Test driving it yourself and making your own mind up is advisable too however!

Although Piolet is set to revolutionise the way we listen to music, it is not without its problems. Providing you are aware of them, however, the two of you should get along just fine. One of the few stumbling blocks you are likely to encounter is having your transfers cut short. This happens whenever the user you are downloading from disconnects from the internet mid-transfer, moves the files you are downloading, or performs some other action likely to interrupt the download process.

You can slice and dice an MP3 track anywhere you like and the remaining portion will still play correctly, which may lead you to believe everything has gone according to plan despite receiving a 'transfer error' message. That is, until you listen to the end of the track and find that it comes to an abrupt halt without warning. At this point the best thing to do is hit your computer as hard as you possibly can while cursing at your nearest and dearest friends, relatives or partner. It won't help you in the slightest, but it may make you feel a bit better!

To avoid accumulating a collection of half finished MP3s I'd suggest setting Piolet to delete partial downloads from within the preferences menu. That way you can perform a new search for the same track and begin again from scratch; a painful process, but one that pays off in the end. Nevertheless, what's even more annoying is when other people fail to do this and instead leave partially transferred tracks in their shared folder for you to find and waste your time downloading.

The best way to avoid this pitfall is to click on the heading of the file size column to reorganise the tracks into ascending order according to their file size. Providing that the songs listed in your search box are of an equal bitrate and have the same track title, the one with the largest file size will be the most complete of the set. When trying to reduce the likelihood of downloading half finished tracks, biggest is best, so always make a beeline for the ones with the most bytes to avoid having your listening pleasure cut short.

If Piolet doesn't float your boat, fear not, there's a plethora of other options available to you. While none of the competition feature cutesy pixelated Blubsies they will nevertheless get the job done (with widely varying degrees of efficiency) - check out my file sharing tutorial for some inspiration.

Ripping, encoding and creating audio CDs

Now that you have a reasonable sized collection of MP3s you may want to create your own audio CDs that can be played through your hi-fi so that you can make use of your woofers, tweeters and any other house hold pets you can lay your hands on! This is a fairly straightforward process, but you have to keep in mind that you won't be able to fit hundreds of them onto one CD because they will no longer be in MP3 format. Before your hi-fi's CD player can recognise an MP3 file as a music track it must first be converted to wave format; the 40 to 50 megabyte files we discussed at the beginning of this tutorial.

When this conversion process has been taken care of, all that remains to be done is to burn the files to a blank CD-R using an audio CD template. To carry out this operation, open your favourite CD writing program and select 'new CD' from the file menu. Now choose 'new audio CD' and drag the wave files you wish to burn from the source files window to the music CD project window, give the CD a title, fill in the artist name and finally press the 'write CD' button in the usual way. Bear in mind that if you burn your collection of wave files using a data CD template your hi-fi won't have a clue what to do with them, although you will still be able to open the files through your PC using Media Player or a similar audio playback program.

Before you begin creating audio CDs and converting file formats it is important that you understand some of the terminology used in MP3 creation/playback circles. Ripping is the process by which audio CD tracks are converted to wave format and stored on your hard drive. Encoding on the other hand is the art of converting these wave files into MP3 format whilst attempting to minimise any loss of quality which may ensue. There is a glut of so called audio ripping/encoding programs on the market which will take care of these tasks for you, but the difference in terms of the quality of the encoded tracks they produce is vast.

The program used to rip or encode audio tracks is not the only consideration, however - these programs are not standalone, but rely on a particular external encoder to produce MP3 tracks. The two best encoders are Fraunhofer and Lame, and to be of any use, these must be used in conjunction with an audio ripper. Many people use the Xing encoder without really understanding its drawbacks because it is the default encoder found in one of the most commonly used audio rippers, Audio Catalyst. Note that Xing is a very poor substitute for the Lame or Fraunhofer encoder because the sound quality is inferior to that produced through the use of the latter encoders. In short, give it a wide berth if you want to optimise the sound quality of your MP3 tracks.

As I said earlier, there are a broad range of options to choose from in terms of MP3 tools, but my personal favourite is Audiograbber. Audiograbber, when used correctly in conjunction with the Lame encoder will guarantee that your rips are free from pops and clicks every time. Combining these two essential components may sound complicated, but it simply involves placing the freeware Lame DLL encoder file into the directory where the main executable file of Audiograbber resides. Audiograbber is completely idiot-proof so is perfect for beginners, and yet has a myriad of more advanced functions which allow the more experienced encoder to fine tune the conversion process.

The reason Audiograbber produces such high quality MP3s is because it encodes music not via the sound card, but digitally, enabling it to make perfect duplications of audio CDs. It also has the ability to analyse the files it has produced for imperfections, which can then be corrected, in addition to eliminating periods of silence from tracks and performing a normalising function to make sure all the tracks are encoded at the same volume.

The interface is exceptionally user friendly so it is usually fairly obvious how things work from the outset, nevertheless, if you're still struggling to get it to work after going it alone, the Audiograbber home page provides some very comprehensive FAQs and walk-throughs to help out newbies.

If sound quality isn't your top priority, however, an even simpler method would be to let Easy CD Creator take care of the whole process for you. With a few mouse clicks this all purpose program will convert your audio CDs or MP3s to wave files and then burn them to a blank CD-R all in one fluid motion on the fly. If you're planning to take this approach, first ensure that you have plenty of spare disk space available to store the temporary wave files, which will be created behind the scenes before being written to the CD-R.

There are two ways in which you can encode your music tracks. The first, as already covered in detail above, is to download MP3 files from the internet and convert them to wave files, and the second is to turn your own or your friend's CD tracks into wave files (known as 'ripping'). With this antecedent dealt with, it is simply a case of deciding what is going to go where and in what order. To arrange your files, simply drag and drop them using your favourite CD writing software.

Before you all rush off to burn your first audio CD, a final point to note is that most modern CD compilations are stored on 80 minute CDs. This means that to copy a CD track-for-track you will not have enough storage space available on your standard 74 minute CD-Rs, so make sure you stock up on plenty of the fifty-megabytes-extra varieties.

Thought for the day - aka the disclaimer bit

Roll on fairly priced, legal music downloads! It will be a monumental leap forward for consumers when we are at last able to pick and mix the music we wish to purchase without paying a premium for space-fillers, or to subsidise the luxurious lifestyles of fat cat, record label parasites. Hell, let's dispense with them altogether and pay the artists directly. With the advent of forward-thinking, internet-based delivery systems for music, let's also hope that less well established, yet equally talented and hard working artists will be able to penetrate the market and receive the recognition and reward they deserve.

(Not so) Hotline

Back in September 1997 before Napster was even a twinkle in its mother's eye and Gnutella was nothing more than a chocolate spread an application known as Hotline emerged opening the flood gates to a world of file sharing opportunities. Sadly while Hotline's radical approach to internet communication created quite a stir in its infancy, the program is now little more than a fancy FTP client with a few superfluous bells and whistles.

Clearly I'm not exactly Hotline's number one fan. If I am to cut the developers any slack at all it would be for having the foresight to recognise the problems that go hand in hand with centrally indexed networks, and for leaping over this pitfall by opting to take the much more future-proof decentralised network path. This feature alone is perhaps the one thing to have kept the program afloat over the years.

To cut a long story short, the software consists of two components; the client and the server. Nevertheless, the backbone of the system is the tracker software which allows users to locate servers and then search for files by name. The client, server, and tracker software can be downloaded from the Hot Springs Inc home page. The client works much like an FTP client in that it allows you to connect to a remote server in order to exchange files. Unlike modern file sharing clients, however, Hotline allows you to choose what you wish to upload. So what exactly does Hotline have to offer over and above your average FTP client? Well you can chat to other users, post messages, read news and ...yadda, yadda, yadda. Who really cares? If people want to interact they'll go to a Yahoo chat room or use an instant messaging program. If they want to download files they'll use an FTP client. The two things, in my opinion, just don't mix.

The server software, in contrast, allows anyone with an Internet connection to turn their computer into a file server, which other people can log onto to exchange files. Pfff, big whoop! You'll have to excuse me for not dancing on the table with excitement, it's just that I've been able to do this for years using Serv-U, and with much less hassle. I wouldn't be such a cynic if the Hotline software had helped to create a community where people actually made files available out of the goodness of their hearts rather than to try and make a quick buck. In the beginning this is exactly how the servers were run, but now they have become nothing more than banner FTP sites where in order to gain access you have to trawl your way through porn sites clicking on banners left right and centre to locate username and password combinations.

What makes this worse though is that often, once you have gone through this tedious process you discover that the whole thing was a money making scam. Analogous to no ratio FTP sites, free access servers do exist, but they are very few and far between. If you are to get any benefit from this program at all you would be best advised to set up a private server between a group of friends. That way you can freely exchange files while side stepping the inevitable banner click scams.

But wait, there's more! More moaning from me that is. Whenever a client upgrade is available, your present client automatically gives up the ghost and refuses to work until you have upgraded it to the latest version. While this makes sense in theory, very often you are unable to connect to the upgrade server leaving you stranded up the creek without a paddle. To boot the program is riddled with spyware and the whole network is carefully monitored by Hotline Communications Ltd.

As the years have gone by Hotline has gradually become more and more commercialised - aptly demonstrated by the implementation of excessive banners, pop-ups, spyware and other information-gathering tactics. Subsequently the Hotline client has become more and more bloated and its stability has declined beyond belief. You'd think the developers would have learnt from their mistakes, but no, they still insist on opening every aspect of the program in a new window as though they are all independent applications. This creates a cluttered mess on your desktop and generally makes the whole interface awkward to navigate.

If you've got any sense you should be running for the hills by now, but for the masochists amongst you who actually still want to give this a whirl, here's how to get started. Once you have installed the software you will need to add a group of servers, known as a tracker, to your bookmarks. Tracked.group.org is currently one of the biggest hosting nearly 2000 servers, so this is a good place to start.

You can also find an up-to-date list of active Hotline trackers at Tracker-Tracker if this one doesn't meet your requirements. Having added the tracker you now need to click on it so that the available servers become visible. Once the server list has appeared pick one you would like to connect to and double click on it. A dialog box should now pop up. If the server requires a username and password enter this information into the relevant fields and click on the connect button.

Now that you're in the clutches of the merciless Hotline server nerds you can download files simply by double-clicking on them. Any uploading you wish to do is taken care of by the button sporting the upwardly pointing arrow - if you click on this a browser window will pop up allowing you to select the files you wish to send to the server.

To search for files first choose a file category from the pop-up menu and enter some search terms in the field next to it. Search queries make use of actual file names rather than keywords, so the search term 'music' won't return any hits unless someone has a file with a name like 'music.zip' on their server. To make it easier to find accessible servers there are also check boxes to limit search results to servers that are online, and servers that allow you to download without a special account. Happy hunting!

So that just about covers Hotline's disadvantages and... erm, disadvantages. Personally I think Hotline has had its day. File sharing clients are getting better all the time, but sadly Hotline has been forsaken in the race to fill the gaping hole left in the market by the demise of Napster. It was good-ish while it lasted, but there are now far better clients around, and since they are all free to download there's no reason for you to settle for second best.

Usenet and newsgroups in a nutshell. Read all about it!

The best way to help you grasp the concept of newsgroups is probably to compare them to something which you're more familiar with. So, just to make sure we're on the same page, picture an all singing, all dancing state of the art forum. Got that? Now mentally remove all the graphics, the pretty emoticons, avatars, signature graphics, the whole shebang really. Now take away the community spirit, the personal touch and the sense of organisation and what you're left with is pretty much the essence of a newsgroup.

They've been around since the beginning of time (at least in internet terms), silently lurking in the background with all the pizzazz of a day out in Scunthorpe - the fact that they exist at all often escapes people's notice until they've been using the net for quite some time. As you can tell I'm not the world's biggest fan of newsgroups, but even I have to admit they do still have a lot to offer. What they do, they do well. They're functional, nothing more. You can get in, get what you want quickly and effortlessly and get out again all in the blink of a weary net surfer's eye, which makes them perfect for leeches and lurkers. Personally I happen to believe that there should be more to online communities than quickie downloads, but then everyone's entitled to their own opinion aren't they.

If it helps to put things in perspective, you can think of newsgroups as public notice boards where anyone and everyone can come along, read what has already been written in addition to writing their own messages which can then be pinned up alongside all the other notes. Each notice board contains messages concerning one or a handful of very specific topics that can be as diverse as the people who use them. The conglomeration of all the individual newsgroups, which literally number tens of thousands, comprise what is known as 'Usenet'.

Luckily for us, each individual newsgroup isn't left to swim alone in the sea of information that is the net - they are grouped together by their general theme and named accordingly to make them easier to locate. Take the 'rec.toys.lego' newsgroup for example. The prefix 'rec' places the group squarely in the recreation category. As we move from left to right we are given more specific hierarchical information which helps us to get a feel for what the group is all about. It doesn't take a genius to work out that the people participating in this newsgroup will be especially interested, or even dangerously obsessed with that timeless kid's past time, building things out of plastic interconnecting bricks.

Most newsgroup prefixes are fairly self explanatory, which is handy because it means that you don't need to consult a newsgroup manual to work out what sort of theme any particular group is concerned with. Newsgroups prefixed with 'alt' for instance, are designated as alternative discussion arenas, whereas the prefix 'news' indicates that a group is specifically tailored to the discussion of the Usenet system itself.

One of the largest categorical divisions, however, is marked with the prefix 'binaries'. You can expect the subscribers of any newsgroup with such a prefix to be most interested in downloading encoded text files, which once decoded can be used in a myriad of different ways. These transformed text files can range from pictures and movies to music and software. The ability to effortlessly harvest this seemingly boundless content represents one of newsgroup's greatest appeals.

Amongst the decipherable text messages you will receive via your newsgroup reader you will find segments of larger files encoded as what appear to be gibberish ascii characters. These can be split up to enable them to be transferred over the net via limited capacity newsgroup servers - this is why they are considered an especially suitable medium for the distribution for spanned, compressed archives.

So how do you reap the benefits of these miraculous resources? First of all you're going to need what's known as a newsgroup reader - Forte Agent available from www.forteinc.com is a particularly good specimen. Alternatively, if you're happy to lay out the welcome mat for malware and let it run riot on your system you can use Outlook Express, which more than likely you will already have installed. If this is the case, all you have to do to get started is visit the menu bar at the top of your screen, select the 'tools' option and click on 'accounts'. From within the ensuing dialog box prod the 'add' button and select 'news' from the expanding options menu.

Outlook Express being the inquisitive creature that it is will now ask you which news (or NNTP) server you would like to use to connect to Usenet. Ideally you would want to use the one provided by your ISP - since this is included in the monthly price you're paying for internet access, at least in theory it should be superior to the free ones available elsewhere. The name of your ISP's news server is nearly always the name of your ISP prefixed with the word 'news' or 'nntp' separated by a dot. For instance, if your ISP is Freeserve, the server name you need to enter into Outlook Express would be 'news.freeserve.net' - if in doubt check the FAQs on your ISP's home page.

My tightwad ISP doesn't provide an NNTP server, so now what? You might want to consider subscribing to an independent news server. Last time I checked, eight-ish dollars a month was the average you could expect to pay for such a service. If protecting your anonymity whilst posting messages to newsgroups is of concern to you, you might like to look into the unmonitored options these companies offer.

Otherwise shop around for a more advanced newsgroup reader - one equipped with built-in privacy protection features. Keep an eye open for the keyword 'proxy' as you explore your newsgroup reader's help files and you won't go far wrong. That said, many proxies aren't really anonymous at all despite their claims to be. To make sure you know which category yours falls into before using it you can perform an anonymity status check using the proxy tools cited in my anonymity tutorial.

A spot of Googling will soon reveal that a minuscule number of public news servers are provided free of charge, whilst the majority have to be paid for. Since almost anything freely available online is going to be highly sought after, you can expect the free servers to be oversubscribed and infuriatingly slow. Nonetheless, if you're prepared to accept this drawback and embrace a freebie server, I would advise you to visit dmoz's list of free NNTP news servers to see what is on offer.

So you've decided which news server to use, now what? You will be prompted to type in the name and email address you would like to be displayed alongside your posts, if you intend to make any. It is probably wise to use a fake name and/or email address here to maintain your anonymity and prevent your inbox from filling up with the spam of unscrupulous newsgroup email address harvesters. Alternatively, you may want to consider using a 'spam only' email address so that people can still get in touch with you if necessary. Whatever you decide, enter this information now and click 'OK' to progress to the next stage.

With these precursors out of the way, Outlook will ask you if you would like to download a list of all the newsgroups available for subscription. Select 'yes' and wait a moment or two while the information is processed. Decisions, decisions, which ones to choose? Tough isn't it? One way of selecting a newsgroup you wish to join is to scan through the names of all the groups sequentially until you find an interesting sounding one, but this is likely to take you all day. A better way is to narrow down the list using keywords, just as you would when using a search engine to filter out irrelevant web sites.

If you're in the fortunate position of already knowing the names of the newsgroups you would like to subscribe to you can tap in a partial address; if they are supported by your newsgroup server, Outlook Express will automatically fill in the remaining nodes of the address for you. Yet if your ISP is especially over zealous with regard to censorship, don't be surprised if no matches are found at all. If, for legal reasons, the newsgroups you wish to join aren't supported by your ISP you will have to go in search of an uncensored third party server.

Once you've found a selection of groups you wish to participate in, simply click on each one while holding down the control key and poke the 'subscribe' button to add them to your short list. If you glance in the direction of your inbox and then cast your eyes downwards slightly you will see that your newsgroup server has been appended to the bottom of the list of folders, and underneath that is a list of the newsgroups you are currently subscribed to. If you select one of these and click on the 'synchronise' button, a pre-designated number of message headers will be downloaded and placed in the area where the body of your emails usually appear. Note that it is only the headers you are downloading at this stage, not the contents of the messages or the encoded 'attachments'. To read one of these messages simply click on the header and wait for the message body to download.

Having lurked in one of your chosen groups for a while you will get a feel for the sort of subjects considered to be 'on-topic'. When you're ready to contribute to the discussions or share a file or two with the other subscribers all you have to do is click on the 'new post' button, type in a subject title, the body of your message and attach any files you want to upload using the 'attach' button.

Surprisingly enough, the final stage involves hitting the 'send' button. If you wish to 'cross-post' - post to multiple newsgroups simultaneously that is - enter the names of all the newsgroups you wish to contribute to into the newsgroup field - separated with commas - and press 'send' in the usual manner.

But enough chat, you want to download the latest digital delicacies, right? Well to do this you are going to have to get to grips with the encoded gibberish text files we spoke of earlier. These aren't really attachments in the usual sense of the word, but since visualising them as such will likely aid your understanding of the process I won't split hairs.

If a message is accompanied with an attachment, a paperclip icon will appear adjacent to the message subject line along with the size in kilobytes of the attached file. Attachments are actually binary files that have been encoded using the UUENCODE format, which to the naked eye looks like scrambled text. This is because to use these attachments as they were intended to be used they first have to be decoded and combined (if they are spanned across multiple posts).

To save an attachment contained within a single post simply select 'save as' from the 'file' menu and choose a place to store it. On the other hand, if the file you want to keep is a multi part attachment you will have to select all the messages the file is spanned across using the left mouse button and control key and select 'combine and decode' from the 'message' menu. Whenever you do this you will be asked to arrange the files in sequential order using the up and down arrows. Complete this task and all that remains to be done is to 'OK' the operation and choose a place to store the resultant decoded file.

Other operations you may wish to perform include replying to a post while quoting the author, and contacting the author privately via email. To perform the former, click on the header of the message you want to reply to, press the right mouse button and click on the 'reply to group' button - a new, pre-formatted message window will surface complete with a quoted text appendage to inform other subscribers what it is you are referring to. To execute the latter task, right-click on the message posted by the person you want to contact, press the right mouse button and select 'reply to sender'.

That just about covers the basics of using a news reader to browse the Usenet archives. Congratulations - that's another new skill you've added to your inventory. Some people hate installing extra software that must be regularly maintained and upgraded unless it is absolutely essential to do so. If you're especially opposed to the idea of using a software client to visit your favourite newsgroups, you'll be delighted to know that you can achieve the same ends by visiting a web based Usenet service instead. News reader or web site? The choice is yours.

How can I force Flashget to download file formats that aren't included in its 'monitor these types' list?

One way to do this would be to copy the link of the file into your clipboard, select 'new file' in Flashget and paste the URL into the URL dialog box, yet it is possible to achieve the same goal without leaving the web page where you found the link. This can be done by holding down your control and alt keys simultaneously whilst clicking on the link. Bear in mind that this technique also works when downloading files hidden behind redirect and anti-leech script links.
