I'm having some trouble uploading an avatar image. Is this a recurring problem? What do I need to do?
Not really. I crop the image, hit "okay," and it takes me back to my profile screen like it worked, but the image just isn't there.
Avatars have to be approved by the Moderators prior to being publicly visible. It was most likely just sitting in the queue waiting to be approved. It looks like you have an Avatar now.
