They've got one ready for implementation but apparently it doesn't look good enough. (I think it looks rad though) I say throw it on live and improve it based on user feedback.

Preview: http://game2.toribash.com/~fear/index.php Instructions: go to the bottom of the page and select "Dark_" from the quick style chooser. It's a dummy forum though so your posts won't show up, and you won't be able to post in the first place at all because of qi limits but feel free to mess around in the help section I guess. Feedback is highly appreciated. I'll poke Fear if you want to see something changed.
