My Spleen requires regestration to control leechers, that's all. Basically, it to get people to agree to share. Bittorrent is the most painfully simple programs in the P2P group. All you have to do is install a client(I recommend Azureus or BitTornado, though any none base program is great), click the link, and the download is just like clicking a web based file. It's not hard at all, and much better than eMule, and simpler than DC++ and IRC.
