It seems all the UO newsletters this year include an interesting paragraph near the bottom. It reads:
If you have an account that was terminated by CS over a year ago and would like to have it back please contact support (http://uo.com/support-welcome/) and give them the details and identify the account as yours, depending on the termination we will remove the restriction from your account so you may open it again.
If you know someone who was banned for a relatively minor infraction, it would be a good idea to let them know they could have their account restored.
In other news EM Bennu added some screenshots of the event the other night to his Facebook page. Go take a look while you wait for the event video!
