Remove 'Managers' from Historic Profiles either completely or replace with a tab of 'Editors', 'Researchers' or whatever name we can agree on.
This will solve a lot of management arguments and the continual sense of ownership of profiles which are everyone's heritage. It will prevent several actions suggested already like when a zombie is killed off giving ownership of the profile to whoever asked for it to be 'killed'.
This could be a case of setting a maximum number of managers before it becomes classed as 'In the public Realm' so that privately connected family is less likely to become 'historic profile' with no managers. There are already profiles with over 500 managers. Do we let this go on to infinity?
