I didn't have a handle at the time. I was still waiting for approval. So to kill time i went to go talk to people in the chat. and named my username in the chat Revanite Opress or something along those lines
Actually you don't need to PM anyone as if it's the autogenerated nick it's just a nick ban. Switch to a unique nick and you should be good to go. Most people use their character name or intended character name as their nick, just needs to be something to distinguish you.
