This may be a selfish request but would you consider moving the original repo to it's own organization? The canonical repo gets a higher placement in search results and for link juice.
Plus if you were to move it to it's own repo/organization, it would allow the forks to submit their changes upstream and have one master repo instead of multiple forks with their own changes.
