Welcome to Librarium Online!
I'm sure this has been brought up before, but is there any reason we don't have a user group for LO Chat users? With a little graphic to go along with the Enhanced Member, etc. user group icons? I think it'd go over well with the chat users.
Also, I personally found that things looked better when all of the groups a user belonged to were in a neat stack under their avatar without space between them, with only the "highest ranked" group's icon being shown. It was much neater, I thought, and I wouldn't mind seeing that put back in if people agree.
Just some thoughts.
