Forums included in the backup

Email to wiki feature

Possibility for embedding "ManyEyes" visualizations

Just a couple of thoughts on how some features could be made more useful

I think it would be a plus if my error console doesn't spawn 30 errors from base.css.

The ability to restrict the tag cloud to groups of tags identified by a leading "category:"

The ability to give groups of members permissions to create/edit in a particular category or subforum, but not others
