I took the chips and set up on a table in the Con Suite and worked out how to divide them out equitably for up to 28 players -- that's the most we've ever had sign up. There are a few odd chips left over, with the additional odd chips set up so we could possibly get a couple extra people in. The other folks attracted to my chip action helped, including catching a chip-stack error I made at one point. They also looked over my payment table (we'll pay 50/30/15/5% of pool for the top four) and offered advice on it and the blind progression and round timing.
And I've had enough people come by asking to be in the tournament that I feel confident that we'll have enough to start with two tables, and that we're above "critical mass."
I've also signed up to use the Boardroom late tonight, so that when we get down to the eight people, we will adjourn there for the Final Table.
