Just to repeat what cryman said, why are some of you complaining about the suggestion? Or the timing of it?
1. I never knew that forums were subject to "one improvement per unit of time" sort of thing. Okay, so we just got a spam filter. What does that have to do with a theme suggestion? Unless one single person manages ALL aspects of the forum and has no time on his/her hands, I don't see why multiple improvements cannot be implemented in a simultaneous (or near) fashion.
2. I'm not pointing a gun and forcing anyone to design it right now. Its a mere suggestion and as I mentioned before, my other forums use it and the members love it.
