This is nice and all but, how the forget would people communicate, or what if someone needs help?
And most likely what if someone gets kicked and they try and come back to talk to the admins but they can't.
Wouldn't it just make sense to make an addon that doesn't show chat messages from non-admins instead of disabling the entire chat?
That would at the very least let non admins communicate, then again their is already the admin chat addon.
