OpenBitTorrent is a bittorrent tracker free for anyone to use. You don't need to register, upload or index a torrent anywhere, all you have to do is to include the OpenBitTorrent tracker URL in your torrent.
When you create a torrent file the application will ask you for a tracker address, then simply type in OpenBitTorrents tracker URL:
udp://tracker.openbittorrent.com:6969
