Coworking - To establish a collaboration space for developers

We rent a coworking space in SF, and it was very beneficial. A bunch of startups share the same space, and we are constantly exchanging information, ideas, contacts, etc... I think that's the most important thing about coworking: It's not much about the space itself, but about the community formed around the shared space.

I looked at the website but I don't understand what I'm supposed to do. How do I get coworking?

I'd like to do this in Atlanta. Maybe that will go on the list.
