Have you found one of the Project: B.H.A.M. QR codes? Sound like something you'd like to do?
It's totally free to play while we're in our "Beta" phase. We're currently using a couple of different mobile apps to keep everything going. First you'll need Slack on either your phone or a computer. Second, you'll need a good QR code reader (although I think iphones have them built in, right?). Third, you'll need to send me a good email address, and I'll hook you up with an invite on Slack. The best way to reach me is either here in the comments, or via my dedicated gmail account, email@example.com.
If you'd like to start fresh with the new round, I'm anticipating the next monthly installment going up in the beginning of April. This gives you a little time to sign up (and maybe talk some friends into playing as well).
