I disagree with ImupChucKing. Just because the rules are the way they are now is no reason not to complain or to advocate changing them. Especially when certain people manipulate them in a way that's only fun for themselves and hurts other participants.
I feel that I was tricked into joining the "-" tournament and have been used for someone else's pleasure without anything in it for me or my permission. Since the rules won't allow Pawns to enter more than one tournament, they're screwed by these kind of actions.
The solutions are simple. Just give participants more say in what's happening and don't force them to stay in a tournament that they've been eliminated from. Any proposed change in the starting date or playing times of a tournament should immediately have a notice sent out to all signed up people that it's happening and they should be given a chance to stay or leave.
And like I said earlier, let the games one is playing count towards his limit, not the fact that some of them are tournament games or not.
