How can I change avatars?
in the upper right of screen, mouse click your current avatar
then in the pop up window, click on it again.
you have the option to choose any jpg or such file to be your avatar at this time.
--- you can also change it by editing your apparel - the game will ask you if you want to save as your profile avatar. I always choose no since i have a different mixed up outfit i wear. yep, i'm not color coordinated and no fashion sense.
