I'd like to have all the PhotoPost products (PP Pro, ReviewPost, Classifieds) all in one. Basically, it would be PhotoPost with the other products as "add-on modules". If there is a review, there would be a link via PP Pro to it. If someone has pictures of it in PP Pro and has it for sale, there would be a link to the classified.
Personally, I would not buy all these products and have them as separate sections unless they were all tied together somehow.
