How do you edit your avatar

At the top bar you will see a bar with the words 'Home,Help,Search,Members,Profile,Messages' Click on profile, that will take you to your profile page. Just click on the button 'Edit Profile' and you should be good to go. Oh and if you want to upload a profile pic, just go to your desktop, on the internet, anywhere on your computer, click on the picture and drag it onto your profile page, just make sure that it's under 500 pixels.

Hope I helped!
