It seems github will be supporting project accounts soon:
This would be very cool. Right now Neuronvisio is hosted under my account name, something not personal, but project centric make a lot of sense. Especially when you have more than one developer.
On top of this there is this amazing plugin for mercurial, which will make git user very easy if they want to collaborate with those.
Maybe Sumatra is going in this direction, maybe not. Back on this soon.
