Don't take this the wrong way, it is just a suggestion. But when a visitor comes to the website and clicks "Forum", I think they're hoping to see the forum straight off, and not need to scroll down 4 or 5 page folds to get to the forum categories. Can you not make separate pages for all the stuff that clutters the top of the forum? Or move the clutter to the bottom of the forum?
Just a suggestion.
