get a life -_-" people don't come on these forums 24/7
i'm perhaps the closest to someone who does, but i have ONE LEG, so i can be excused thx very much...
go to your profile and edit it from there, your avatar (as explained on the site, read it next time before you ask) has to be less than 7kb in size, no bigger than 100x100 pixels... you can make your own, if you like, enjoy
