for now, this is a complicated app to think of more features....
But one i will suggests that comes from my members....
Maybe have special custom button or badge that gets produced by being verified, one that can be displayed on banner or in the default sidebar somewhere?
So to put with that, i would say allow the admin to make some custom text, or have some custom colors for the badge or button?
I will be thinking of more, cause this is a good app, and i hate to see it lose its richness of good use (no disrespect)
