@mhoeber @lamagnifica @stephensanchez @wedaly @gradyward Please review. This is a draft so things may be a little rough around the edges, and I have a couple of notes to myself inline.
in a test course? so, they have to do all of this all over again? yikes. I'd say that right up front, that doing this in a test course in order to evaluate the way it's set up is something to consider or plan for... But, couldn't they instead set the section/subsection/unit date in the future, and give the beta testers early access (through advance settings) before that date?
