Our meetings are run very casually and we discuss interesting and fun topics. We start off by choosing a meeting leader somehow.
This meeting leader gets the "Theptor" and controls the flow of the meeting and appoints a note taker.
We then go around the room and give everyone 6 minutes to talk about whatever they want. A guideline is provided on our wiki.
It is a lot of fun and we usually get food / drinks if enough people show up. http://hackerspace.eventbrite.com/
RSVP is optional. Just show up.http://internetweekny.com/events/506
