GitHub at the university

We get to learn Git at the university, but you never really get the full potential of git until you use it hosted somewhere, like GitHub for instance.
This is why I think this should be a part of the university courses too.

I recently used it when I implemented a card game in java. We had several steps we had to take to get the code working. It was important to be confident that if I tried something experimental I could later rollback to an earlier commit without being afraid of having lost work because of the experimentation.
