Contact MarcWeber using the github page to get push / commit access I would have liked to create a repository which is easier to get access to (eg by registering at github only) But I didn't find a way. I'm fine with creating a more neutral name such as github.com/urweb later if several users start contributing. (I also tried gitorious - but got yet another "I'm sorry" error .. )
