Hey guys i am new and i need all the help i can get i have look every i can think of plz tell me thanks guys.

Top right corner of screen, click edit profile. About halfway down, you can change it there!

Look at the very top of the website (scroll up if you need too) and find the "Edit Profile" link and click it > scroll down to the Avatar section > click "Browse..."

There you go. Hope that helped.

Thanks guys
