For our group in particular:
St. Louis Game Developers
STLGameDev was created to help collect and centralize all the latest information and events happening in the St. Louis area that focus on game development. You can always find a countdown to the next GameJam, Meetup Details, Contests, and of course an aggregate of local blogs and other feeds. If you should be included on this site just let us know!
