I was afraid of that. Unfortunately, because I'm on the site through my blackberry phone, my options are limited. The browse button is there, but my blackberry will not allow me to select it. So unfortunately for me, I can't upload a picture as my avator. I've looked at the choices given by the site but I saw none that caught my eye.
So I guess I have to deal with the handicap my blackberry gives and unfortunately deal with the idea of having no avator until I get an actual computer. Thank you anyway.
