Another way to search/get files is to use Shareaza (hXXp://www.shareaza.com/), which connects to several other peer-to-peer networks such as eDonkey, eMule, and others. It's free and more user-friendly than USENET, although not as convenient as a good torrent client connected to this site. I use that protocol to get files that I subsequently seed here (damn, there goes my secret!). If you do use the Shareaza client, though, I recommend against using it for torrents–in my experience it's much slower and clunkier for that than uTorrent.
I don't know if further discussion on that belongs here, but feel free to PM me if you have questions.
