I am not a big one for changing avatars. I used to for years use a picture of Patsy from Monty Python's the holy grail until one to many people let it slip that they thought it was actually me (a mate of mine used a picture of Mat Lucas in his wheel chair until he realised that all the foreigners he spoke assumed that was really him too.) Now I just use an actual picture of me or occasionally one of my boys. I have been using the same name on line for about 15 years too.
