I've been a Meetup organizer for 4 years. I've started several free groups. People need to realize that they are dealing with human beings on 3 levels. 1. Meetup New York. 2. The group organizers. 3. The members. Most organizers are good people who work without pay. Most members are good people too, but expect to run into anything. Never carpool with someone you don't know well. If Meetup members didn't love their groups they wouldn't stay in them for years, and that's the bottom line.
