Lol there is no such a thing! The teams themself pick their levels:P But they have to pick the levels from the tournament's mappool, and the mappool is chosen by Jerry and Sucer from the level suggestions that you post here. So far the mappool has bblair and semi. You don't need to suggest the same levels again.
So this tournament rely's a lot on the other team's cooperation. It's just for fun, so keep it fun.
Of course depending on how many teams sign up and how good the teams are the winner get's a little fame and glory.

So if for example Sasik Maverick and Nunez sign up and they would choose the same levels as team 17r has chosen, they can play cruel and choose some evil campy levels which everyone hates (including themselfs) like Zaitox station. They never choose the level in an actualy game, but they pick it to the mappool just to annoy the other teams.
