I think putting the search feature (not the google one on the left.. that blends in with the ads) but the search forums/threads piece right on top of the home page. Optimally between the "BlackBerryForums.com : Your Number One BlackBerry Community" and forum listing.
You know as I type this.. I did not search for this topic.. would that not be hilarious
Anywho.. my thoughts. Got to be esaier to focus folks on the search function.
