Apart from non-certified persons who are already profile managers, an even greater mystery is why persons who are not able to edit a pre-1500 profile are able to adopt an orphaned pre-1500 profile.
I will currently adopt all pre-500 orphaned profiles that I see, and many other pre-1500 orphaned profiles in which I have only a passing interest, purely to protect them from persons who are unable to edit them.
I'm hoping that project management of profiles will be something of a stop-gap to address this problem, and after doing some editing on a pre-1500 profile that I don't want a long term involvement with, will ask a project to take over management of it.
