-* list of registered users
-* a [[todo/link_map]]
-* [[todo/sigs]] ?
-* [[pageindexes]]
-* Wiki stats, such as total number of links, most linked to pages
-* Support [[RecentChanges]] as a regular page containing a plugin that updates each time there is a change, and statically builds the recent changes list. (Would this be too expensive/inflexible? There might be other ways to do it as a plugin, like making all links to RecentChanges link to the cgi and have the cgi render it on demand.)
-* Support for smileys or other symbols. I appreciate the support for check
- marks, etc in other wikis. Needs some free smiley files.
+* 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?
