My vote is for the simple design (preferably the current one, but if there is a new re-design which is also simple, I will take it). Don't follow other forum sites where I don't even know whether I am reading a post or an ad or something else.
Keep the colors dull. Let the information be the highlight of the forum. It has been like that and that is why it is very successful and keep it that way.
