+ > 1. The second case above is now just a special case of 1 where _foo_->_foo_ for any
+ > unknown _foo_ is just a copy, and no other transformations apply.

* 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
