As Chuck is short for Charles, here are some other avatar options...
You could choose depending on your moderator style.
Charles Bronson. The cowboy of EvC.
Or how about Charles Barkley? A good sport.
Charlie Chaplin. Amusing and silent.
Prince Charles. Has a crown but is not very important.
Charlie Brown. Everyone loves Charlie Brown.
Charles Darwin. Irony?
Charles Manson. I wouldn't pick this one. Might send mixed messages.
I could agree with you, but then we would both be wrong
