There shall be no pull requests to my Github. BTW, a pull request is a way to ask some other owner to change their code by pulling your commit.

Now you have to push your own completed HW3 somewhere. Where do you put it, you ask? Your own Github repo.

That is, once you have set up your own Github account, you fork someone else's repository to your Github. The fork is now yours. Then you can push your changes to your fork. Richard and Sumanth will grade the code in your fork. 

However, if you do notice a bug or some other problem in my code, let me know about it in issues.
