You can RSVP to the RPG Open House on Facebook or Meetup. There you'll find more details, but the quick rundown is:
Offer to run a game of your choice as a game master! New game masters can gain additional support, too!
Come as a player to join a new game!
Identify one of several welcoming venues to schedule your first session!
New to it all? Come on by and see what it is all about!
The more players the merrier!
