A BitTorrent Client is a program that will manage all of your downloading and uploading you do using torrents.

There are many clients out there, each offering different pros and cons. Only use one client at a time, as using more than one won't make your speeds better or anything.

Here is a list of recommended clients you can use:

• Azureus - complex and a resource hog, but lots of excellent help available
• uTorrent (aka µTorrent) - very easy to get started with

Here are some more clients:

• ABC (aka Yet ABC) - easy starting point for n00bs
• BitComet
• BitTornado
• BitTorrent - not really recommended
