I am not sure why you work off the assumption my avatar choices would be inappropriate by the way. That sounds a tad prejudice, just because I am Satan doesn't mean everything I do is bad ;)<quoted text>
Not sure why you say you're not allowed to have an avatar. The only thing I can figure is that you've uploaded inappropriate avatars and they did not get approved.
I can't approve any avatar until I see it, so I don't have an answer for you.
