Github style forking / pull requests
Created by: Efpophis
One of the nicest things about GitHub, imo, is the fork / modify / pull request method of collaboration. The merge requests as currently available are nice, but what they lack is the ability to request a merge or pull from one repository to another.
In particular, it would be nice to be able to fork a repository that's read-only to me, make changes to my fork, then submit a pull request that can only be applied to the original repository by someone who has push access.
