For one I don't want my PSDs public, and to combat your other questions, why don't we use skype for everything.
If you don't want things public, you can always PM people stuff. We shouldn't create a private area for a small group of people just because they want a place to post something privately unless it has immense value. For example, we have a private area for scripters because the whole site is about scripting/bots/etc; we have a private area for VIPs because they keep the site up and running; we have a private area for staffs (I assume) because they are the people that keep the site clean and under control. As cool as graphics are, having a private area is pointless. I am not saying we need to use Skype for everything, I am saying it is a way to keep things private similar to using instant messaging, email, PMs, etc. Hope this clears things up.
