I don't know about calling them community leaders; someone has to find a place to have the meeting and let people know about it. That can be done without the entire meeting conforming to their personality. But at the end of the day, someone has to do some legwork or it just ain't gonna happen.

The community leaders in this scenario aren't leading the meeting. I guess it depends on the format of said meeting.

In my case, they really just set the location and time, in addition to making sure nobody is causing trouble, littering, etc.

Other than that, it's a free-for-all.

I think its more subtle. Whoever is organizing is setting the tone/nature of the meetings.

For example, there is a chess club I wanted to participate in, but the organizer always picks some loud bar, which just isnt my idea of a chess club.
