I'm sorry you did not enjoy the chat. If you wish to change the "Yellow Tang", you should be able to do it by clicking on "My Settings" and going to Profile.
I have been meaning to make an announcement of the availability of that feature. I've decided to open it up (despite objections voiced to me privately) so people can further personalize their presence here.
We're still holding fast on the "no huge pictures of your BMW and dialup-choking 40kb avatars" guidelines.
