I've had mine for about 30 seconds or less. Do I win?
Change it back!
I am terrible at remembering names, I remember people by their avys, so when they change them I have no idea who they are. I'm even talking about people who have been on here for years. I just connect with the image, so once it changes I lose that sense of identity or recognition. That is part of the reason I haven't changed mine, in case other people are more familiar with my image than my user name.
