I think the longer someone has an avatar the longer it takes for me to adjust. If you want to change go ahead, I am not the avatar police and I will not hold it against you. I might call you out on it but it isn't that big of a deal.
I actually like my avatar now so I might keep it for a little while as I have only been using it a couple of months.
When I read your posts, I sometimes use Charlie Sheen's voice.
