Sometimes it's good to have someone basically forcing you to make time to improve a lingering situation. Subversion was a long time a bottleneck (literally in I/O, and figuratively in collaboration) in RPMforge. I also had been using our public Subversion infrastructure for some unrelated Open Source projects.
So thanks to Yury V. Zaytsev (!) we are finally undertaking the migration to Github infrastructure. This will also mark the beginning of the project's name translation from RPMforge to RepoForge.
