Everyone's beloved Profile URL just became better:
mike.simbunch.com/component/option,com_smf/Itemid,26/topic,721.0/

Most distinct upgrade:
*ALL* links to user profiles (all around your site) will display in the www.domain.com/user format. And as usual, users can change their own profile URL via AJAX.

Requires CB 1.2 and mootools.
Works with both Joomla 1.0 and 1.5
