I believe the rule is that if you are not the merchant selling the product, you can talk about a product on this forum (or its related forum) but if you are selling, or may sell in the future, the product, then you are to place the threads on the Product Showcase Forum. That's the distinction, in my mind. Of course Daz stuff is discussed here all the time, rather to an extreme at times but without censorship, but it is not Daz that's posting but rather enthusiastic users. That wasn't always the case, but it seems to be so now. And there is a distinction between free stuff and selling, of course.
