@gwprice , @jimabramson , @marcotuts , @lou-wang , @explorerleslie , @WatsonEmily  please check accuracy and completeness (note the files have different audiences, staff vs. students).
@mhoeber @srpearce please copy edit.
If we do, I would love to hear it. @mslotkeEDX , this list control is not explicitly identified in the UI. When you look at the page, I think it's pretty clear, so I don't have a problem with there not being an explicit label for it there, but it does make describing it awkward. (we have moved away from using "threads" for the items that are listed by the way). Would adding a callout to one of the images make this clearer?
