Kick me if you like, but found a theme on random inspiration searching and loaded it up. I liked it enough to port it to the main citadel.
It is called "Angel Fall First" and you can change your theme to it in your forum profile.
Profile -> Modify Profile -> Look and Layout
There will be a "Current Theme" label, the name of your current theme (probably Citadel 3.0) and then the (Change) link. Click there to change it. Browse for Angel Fall First and the entire site will update.
Go there and follow same thing to change it back.
If you find other themes you like, it only took me about 2 hours to port it over so would be happy to customize. Main issue is needing a solid starting point.
Drackler, send me that link again.
