I've fired up a group for us at http://atheistnexus.org/group/rrs
If you're not familiar with the site it's similar to MySpace or Facebook but far less cluttered, has a better structure, and is generally not as crap as the others. It also looks nice.
I also have a profile up on there: http://atheistnexus.org/profile/mustard
Hopefully this will net both sites a kickback in social networking.
[Mustard we love ya, but we're closing this thread until atheist nexus works out it's early controversy]
