Clarification on GitHub organization and user access

[lejonmanen]

I've been using this workshop on my frontend students. It's a little unclear whether the repository needs to be created in a GitHub organization or if it could stand alone. A clarification in the beginning of the workshop would be nice.

We've run into a snag in Step 8 - Create a pull request. "Programmer 2" does not show up when we try to assign the pull request. We solved it by giving "Programmer 2" Member access to the repository. Is this the intended solution?
