I don't know if this is a particular topic that would be perfect for Chat. There are many other avatar topics that appear in the SPAM Board actually. Because I'm not confident, this topic will remain here for the moment. If the discussion turns into brainmush, then it'll be moved.
You should have an avatar that isn't obnoxious. I am not saying the previous one is though, haha.
Just find which one suits you best and keep it up. I always got a picture of "The Scream" ready for you.
EDIT: Never mind, I noticed WcW's thread after reading this. Let it stay. Let it stay...
