1st, get yourself a bittorent client, i.e.
http://www.bitlord.com/download.php
that link should start of your download for you.
2nd, tweak your client up for max performance, make sure your listening port is on, this make your downloads a bit faster, set your upload speed to 12 k/s, this won't clog up your system so better downloads.
3rd, logon to a torrent search site, will put links up below for ya. Do a search for the film, app, music etc... that you want, click on where it says download torrent, and bobs your uncle and fannys your aunt, a ??? while later you will have your download.
www.torrentspy.com
www.demonoid.com
www.isohunt.com
www.thepiratebay.org
I only really use the top three, I used to use piratebay quite alot, now it seems to have changed, and I don't like it anymore.
Hopefully komp will be along sometime soon, with his massive
link for torrent sites, sorry komp if you thought i was gonna say something else. lol
