luv, I just did my first torrent downloads last week with Hard Knocks. And on that thread, there's a lot of information there.
Basically, I've gotten this far:
You download a program like this:
http://www.utorrent.com/
After that's done, you go to a website like this:
http://thepiratebay.org/
Find what you want (Grey's Anatomy Season 3) and download that torrent using the utorrent program.
