as such things are a bit outside the already very broad scope of DaniWeb, which focuses on development and IT.
Isn't it best to be diverse? I mean, look at Google... they are not just a search engine. Or even a competitor of yours, Stackoverflow... they have many different forums that are completely different from each other, though their users who answer your questions abuse the new users and their environment and everything sucks...
Honestly, I would love to see a new forum on daniweb that would contribute to people like designers who use photoshop/illustrator and so on. Though, the con would be that not many people would use it because Daniweb has been established very strongly as an IT and Development forum. Also, i don't see room on the navigation for new forums... unless you create a subdomain.
