We will use GitHub to practice collaborating with source control.  

Please sign up for a free GitHub account at http://github.com if you don't already have one .   When it prompts you to pick a plan, select the free plan.

We need to give access to our GItHub repository so you can edit files.  We'd like to take care of this beforehand, to make best use of everyone's time.  

Please tell us your GitHub username below.   You may get an email from GitHub that lets you know you've been added to our project.
