Just a thought due to my recent adventures learning PHP and playing around with stats and such on the site. I've been using the Rake/Fee fields to store numbers for stats and just thought it would be kind of useful for non-developer types like me who don't know how/want to create a separate database to store info that could be useful on the site. So I figured I'd throw this out there and see if it sticks.
Add some more "custom" fields that could store some information on users that can be pulled up via the API on stats pages (or elsewhere, like mouseover at tables) and allow their names to be editable in the Language file (as Title, Custom are now).
