What is BitTorrent.org
This is the official website for the BitTorrent protocol and the current list of (proposed) extensions. The site also describes the process for proposing new extensions to the BitTorrent protocol.
BitTorrent.org also has community forums to discuss the protocol, extensions, collaboration with ISPs and various other important topics. It is not for end-user support, but for more technical discussion about the protocol and related topics. Many developers from different BitTorrent clients participate on this forum.
