Hey,
at http://thezwarm.com you can add yourself if you don't have many friends, but you still want to use the greate program OneSwarm. This is not a way of trying to fish keys and ip-addresses.
It's truly great that it popup different services around OneSwarm, and who knows after a while when OneSwarm is equally common as skype/msn we might not this different services around it, but for now we need.
Keep on rockin' in the free world!
cheers
