Is this just a tournament against everyone on HERE? If so, where do we go to play? I'm guessin' it's on-line, right?

Sign me up!

The tournament ended in July. There is, however, another one starting in the not too distant future. Start practicing.

Yes, since this tournament ended a long time ago, this topic i'm afraid is pretty useless for now.
A new tourney, as mentioned by colorless, will be starting soon, keep an eye out for that.
