I think it would be good to have an area in the forums where admins can talk and stuff without being seen by members so. Also it might be cool to make a donator status on the forums and make a forum area for both admins and donators and the colors of the status goes something like this:
Admins are green like they are
Donators are blue
And admin donators are purple or yellow
Also maybe make it in a way where donators also get stuff in the forums like extra pm and maybe an email hosted here

that would be nice.
