The problem is that it's illegal to make a model of a real person without their consent.
If we had such a thread, it would be full of "Hey, I have some pictures of a girl from my class, who can make me a model of her" type posts, which is illegal, creepy, and a very bad look for Vam.
No doubt Vam users are commissioning all kinds of things from each other. People are gonna do what they're gonna do. But there's never going to be a channel or thread on any official Vam site that facilitates this.
