Users restricted from editing own profiles I found that non-site-admins cannot edit any of the custom fields attached to their profile. I have found the Organic Groups (fixed) feature request "Authenticated users cannot edit his custom profile fields" that appears to explain the issue, but that's not clear enough for me.

Who exactly is the Group Audience for the User (the User?) and how do I set up the settings correctly to ensure all users can access and view their custom profile fields?

Is the User a "Group" and the Custom Profile Fields "Group Content"?
It turned out that the permissions needed to be rebuilt as well as verified that that the user had the ability to edit the "Group", which are actually there own user profiles, albeit confusing with the labels.
