hedger: It is easily possible to make a group and knockout tournament with no hassle at all.
If you (or someone who is willing to donate) has some credits, a group stage can be organised, and then a knockout stage from the best 2 or 3 from each group. So if this is the format, all you will need to do is send invites for both leagues.
Just need the donators.
Btw, I am not 100 % sure of participation as I am committed to LMSC, but if whatever reason that falls through, I'll come play this. Depends on what day the tournament will be played on.
