"Sigh. So, what.. merchants aren't supposed to do artwork and post it anymore?"

Not at all, I fully support it. What I DO think needs to be in the showcase gallery is the gratuitous advertising. You know the type of thing...

"I have had a chance to test ___'s newest creation ___, coming soon to the Marketplace! She/it is great to work with and is just so beautiful! Thank you so much ___ for letting me play with him/her, what a generous gift, she/it is really a must have for everyone on the planet who uses Poser."

This is abused, and I think it is fairly obvious to anyone who looks at the gallery.
