I just posted a torrent and put http://dctorrent.com:6969/announce as the tracker URL.
Next i created the post in appropriate forum and uploaded the torrent file created. Then i downloaded that torrent from that very post and loaded the trackers from it.

But now when i'm seeding i checked the torrent URL and it keeps changing between the registered tracker URL and the first one http://dctorrent.com:6969/announce
Whenever it checks for http://dctorrent.com:6969/announce it gives an error "unregistered torrent pass" but gives torrent status as "working" for the registered URL.
Now wat i wanna know is that only registered tracker URL is of use and the unregistered one shud be removed or not ?
