I have one other question... Why isn't the "Admin" tab called "Users"?
I was just curious because as I've been playing around, I would occasionally get tripped up looking to manage users (obviously forgetting it's under "Admin"). I mean, the only function the tab serves- as far as I can tell- is to manage users, user assignments and user groups. I know it's minor, but I feel more intuitive to call it "Users". Just a thought.
