Well, I've just checked and the situation is still the same with the comments: some images have the comment box, others don't. And it's not because the artist did not enable comments: there are many images which have several comments already, but do not have the comment box to post new ones. I agree about the credit issue people are raising here: one should be able to credit free stuff providers, non-Renderosity artists and themselves, not just the 'Rosity vendors. But the best thing would be to go back to the old design anyway.
