There are two singleton patterns posted up and while I can see which is more recent, I can't tell by how much. It would be cool if you could pull in and cache a "last updated" date from the Github API.

The reason I say cache is because one of the two singleton's appears to have been removed. Another good thing to add would be a job system that checks the integrity of the links—if something 404's after several weeks, it should be removed from Forge.
