I am sure this question was asked before.I am new to this forum and still trying to figure out what is where and how am I supposed to add an avatar? It seems my personal page isn't the solution. Thanks for the help.
Above the red bar at the top , you should see a thing called "SETTINGS" . You click on that and on the left side of the page that comes up , it should say "EDIT AVATAR". You click on that and a page comes up that lets you pick one that JREF offers or you can post your own. I think you are limited to size of 100 x 100 pixels and around 90 KB of space size. If you have trouble there , let me know and I'll try to help you some more. Welcome to JREF by the way.
