Can I login from different computers?



Yes, the tracker is now capable of following sessions from different IPs for the same user. A torrent is associated with the user when it starts, and only at that moment is the IP relevant. So if you want to seed/leech from computer A and computer B with the same account you should access the site from computer A, start the torrent there, and then repeat both steps from computer B (not limited to two computers or to a single torrent on each, this is just the simplest example). You do not need to login again when closing the torrent.
