New to git, so this is hopefully a simple question with a simple answer.

I forked a repository on GitHub. I then cloned it on my local machine by using the public repo URL: `git@github.com:samuelclay/django-mingus.git`, as opposed to the private repo URL: `git://github.com/samuelclay/django-mingus.git`.

I made some changes to the code, committed those changes, and in order to push my changes up to my forked repo, I issued: `git remote add upstream git://github.com/samuelclay/django-mingus.git`, and then `git push upstream`, but while that doesn't give me an error (it says Everything up-to-date), it is certainly not pushing my changes up to GitHub.

Is there a way to change to the private repo URL? Is that even necessary?
