Not sure if everybody here is familiar with couchsurfing, for more info see http://www.couchsurfing.org
My proposal is to set up a couchsurfing network for hackerspaces. We could make a group on the couchsurfing website, and I think it would be a rather neat thing to do.
I am unsure if anybody here at TCmaker is involved with couchsurfing? If you are weary about it, I can re-assure you that it is awesome.
