Color scheme really needs to not be seriously obnoxious. The green and grey and yellow was terrible. I have one of the non-default color schemes set for the forums as it is, because anything else is really hard to read and the revolution roleplay/theme exacerbated it. Speaking of, taking the roleplay/joke beyond April Fool's Day is...well...not my cup of tea. If I wanted to roleplay or see roleplay on a regular basis, I'd have joined a forum for that. So keeping the joke to April Fool's Day would be another suggestion.
Sorry to be a Negative Nancy, but you asked for ideas.
