 * list of registered users - tricky because it sorta calls for a way to rebuild the page when a new user is registered. Might be better as a cgi?

-* It would be nice to be able to have a button to show "Differences" (or 
-  "Show Diff") when editing a page. Is that an option that can be enabled?
-  Using a plugin?

 * For PlaceWiki I want to be able to do some custom plugins, including one
   that links together subpages about the same place created by different
   users. This seems to call for a plugin that applies to every page w/o any
