Barb,
Shal, this is fantastic! Is all of the information current?
Probably. Some of it might be "ahead of current" if there are revisions that Mark hasn't (yet) incorporated into the official help page.
If you spot anything that isn't current or isn't clear please correct it.
Can we copy and paste to use in the Wiki in our groups?
Yes, of course. But as with the official help page itself (which has handy permalinks on sections) the stuff in the Mockup is publicly readable, so you can also link to it rather than copy.
