The new social networking site www.HashSpace.com is getting a fair amount of hash attention at the moment. There is a BAH3 group there, although how it will be used is yet to be seen. You need an invitation to sign into the site, so if you are interested I recommend sending an e-mail to the BAH3 Yahoo list requesting an invitation and I'm sure someone who knows you will send an invitation.
I'm personally not a fan of the MySpace, Facebook, etc. sites and have no idea where this will go, but I figured what the hell I'll give it a try.
