I have setup a GitHub account for the Preston HackSpace https://github.com/Preston-HackSpace
We can talk about access rights once we understand better how to administer the account with multiple users.
From what I know of GIT, I think it is better to limit the direct access to this account to two or three people. Any new projects can be initially uploaded by these individuals and then all further development is done by members through forking the repositories and then making pull-requests to have their patches integrated into the main fork. But lets discuss at a future meeting.
