In my 7.0 install I find that if I login, click on "My Stuff" and then go to "My Profile", no controls are shown in the UI for changing my avatar.
I have:
- "Allow Remote Avatars?" set to NO
- "Allow Stock Avatars?" set to YES
- "Allow Uploaded Avatars?" set to NO
If I set "Allow Uploaded Avatars?" to YES and look at "My Profile" again then I see UI for modifying my avatar. If I toggle it back to NO then the UI goes away completely again.
