Renderosity is one of the Poser "mega" sites. I imagine it's a job keeping up with the content on the main site. I can't imagine doing it on TWO and paying a royalty fee for being there on top of it making less when they already have a very popular site of their own that is probably a major task to manage all by itself. I can see a lot of reasons for the split up. CP is a great place for smaller organizations with a store of their own that need a high traffic hub. Renderosity doesn't need somebody else to be noticed. If anything Renderosity is one of those places you go to get noticed.
