I went by the field and asked on Friday so here's what I gathered...
13BPS ramping, unlimited paint.
Brackets will be set according to the number of players and then there will be a round robin inside the bracket so 5-6 games, high number of wins moves on so everyone should get quite a few games.
He's starting at 1:00 after a team practice in the morning.
There is no preregistration, show up, play. There should be a pretty good number of people assuming some of the guys hold over from the practice and others show up as well.
I'd e-mail him for confirmation on all of that, but that was my understanding of how things were going to work.
I'm also hoping for some open play afterwards, I guess we'll see. It should be a great time though.
