Soldant recommend BitLord for managing torrent downloads. I second this since the program is open source which means anyone can examine the code. Helps to keep it clean, efficient and free.

www.TorrentSpy.com, which has been a valuable resource whenever I download large files, such as the latest linux distro.
Torrents are useful for popular files. I recommend downloading mIRC and
www.ircspy.com for obscure and old files.
