I am instructor at a State College and use Wetpaint Wikis in all my classes. They are great and need only a few minor technical adjustments for being super. My suggestions: Downloading projects/pages, Bookmarks on pages, Edit Notes on Wetpaint-mailed page-change notifications, time-stamps in pages for ongoing collaborations in one page (the old ~~~~ of make-up wikis, but please use only Initials, date, and time), and site backup as intact html website(thanks, you started this option on 01-16-2007).
