I don't want to hijak this thread but it looks like it took a little time and effort to get this up and running.
I'm boot srapping a mastermind platform for this exact type of thing. Custom made meeting rooms with checkins, goal setting, note taker and also reminders to complete your goals (via email)
We have about 120 beta testers but I can easily add your group to it when we start testing next week.
Let me know if this is something that your group would be interested in.
