I had heard of www.suprnova.net or something, to download files using bit torrent. Are there any other, free sites like suprnova?

In my Favorites are http://novasearch.net/ and http://isohunt.com/.

also http://www.torrentbox.com/

BitTorrent is great if the file is seeded well. When I tried BitTorrent, most of the files I wanted weren't that great in terms of seeding... so that kinda turned me off.

But the idea is still great, possibly rivalling the now-all-but-dead Napster when it first came out.
