Where is development supposed to happen on GottenGeography?

Hi,

I'm hit by: https://bugs.launchpad.net/gottengeography/+bug/1582287 and wanted to try to fix it. I now have gottengeography opening, but I'm not sure where to push my changes -- where is the main/most up-to-date code repo? This seems more up to date than https://github.com/marcoil/gottengeography but it says that "This branch is an import of the HEAD branch of the Git repository at git://github.com/robru/gottengeography.git." and that no longer seems to exist...
