I basically made a category for everything, you can pretty much fit anything into the Bidding Directory somewhere. As time goes by I am promoting each individual category which I beleive to be really important for a few different reasons. By promoting your inner pages you are creating a chance to have PR on your inside pages, which will help with your frontpage PR, also by bringing people to your inner pages you increse your overall traffic to your site, which in turn leads to success.
