Problem seems contagious...
click on user cp (towards the top of the page)
click on avator
scroll down the page & you should see where it says custom avator with a browse next to it-that is where I download from a disk to add my personal avator.
now some people are only finding that you can add avators that are already showing...not your own avator. Usually you can add your own,but a few members are finding that since the update they can't add their own avator....moderators can add avators,so if you need help let me or another moderator know & we'll try to add it for you.
