Steve,
We use to have a game every so often on Saturday. Just a regular tournament though, nothing over the course of so many weeks, with a prize at the end. At the most, we had maybe 12 players one week.
Is this going to be on Poker Stars? If not, I don't think you have much chance of getting it off the ground with enough players. I might play every now & then, but would not play every Saturday. Andy - Las Vegas
