$10 is a one-time fee for the WHOLE game, right?
Each event will have a buy-in (5.50?)?
All quirks/twists should be predetermined and "sealed" until they are revealed to everyone. That means that if Cali (for example) is going to play on a team, you should have no part in coming up with the twist revealed half way through (includes how and when merging and player swaps will happen, rewards,hidden immunity!, etc). Someone (trusted by all parties to keep the secrets) needs to play the host/organizer and implement all of the surprises.
You COULD come up with the structure for the hidden immunity (for example) as say a certain winning hand shown down during a certain event (or set of events). Then the host chooses the actual showdown hand (Jxs or something) and the game(s) to be included (2nd-5ths events) and then watches all the tables for a Jxs to be shown down as a winner and the first time it happens that player has immunity. That way, the actual cards/games are secret but you can still be involved in the planning to some extent (Seems like you would like to do that based on all the interesting events you come up with

) or you COULD just be the host.....
I could put together a little summary page/blog/site with some cool graphics for this.
IMO, this should be figured out by next week and then start the week after? Similar to the TP League thread, there are a lot of little housekeeping issues that need to be spelled out before this starts to avoid disagreements 1/2 way through when there is money/prizes on the line.
I am in, sounds cool.
Also, How many teams will there be? 2-3, 4, 5? How many players per team?
