Editing the "myOtaku" page...help?

Hey guys...I've been gone for so long...does anyone know how to change the information on the "myOtaku" page? Because I am not 17 anymore (I haven't been 17 in 2 years haha), I am not in highschool, and I would like to change the pic I had up there. So if someone could just give me a hint or something, that would be greatly appreciated! Thanks! :)
