Admit it, you've been waiting for this day since the server went down in 2007. We've brought the master server back online and everything is so far stable. You'll need to download a new client to play, so go on over to http://www.tnet2.org to get the new package.
Some usernames may have been accidentally deleted in the move, so if you have some trouble logging in, try making it again.
Thanks, and enjoy.
