you cant have one. Something about the code that limits users that start with the letter "L" totally wierd. I have been complaining to management for years about this. They just get hostile when I bring it up now.
ok, so I am just messing with ya. If you go into your profile/private message area on the left hand side there is an area where you can click on edit profile. Then there is an option to edit avatar. If you scroll to the bottom of that page there is an option to upload an image from your computer.
Hope that helps.
