I've just finished a first draft of the instructor-facing documentation. I have a couple of questions for devs inline (search for "SP"; some of the SP comments are notes to myself or the doc team--sorry for not specifying these better). Please review and let me know what you think.

To see a built version, go to http://draft-sylvia-2.readthedocs.org/en/latest/Peer_Assessments/PeerAssessment.html.

I know there will be some UI changes, and I'm planning to update screen shots as necessary next Monday.

Oh: Just look at the PeerAssessment.rst file below--ignore the giant ORA.rst file. I added that one by mistake. PeerAssessment.rst is only 299 lines long, unlike its 740-line behemoth of an older brother.
