I recently persuaded some of my family to join WikiTree. When they accepted the invitation, I was dismayed to find that I was automatically removed as manager of their profiles by the system, which also automatically changed their privacy from yellow to red.
In all these cases, the new members are not especially computer literate, nor do any of them know anything about genealogy. I managed to get them to express at least a little interest and promised to take care of everything until they get up to speed, which none of them (unfortunately) have seemed especially interested in doing.
Two, who were interested enough to add profiles for some of their family members, managed to add duplicate profiles by adding the other parent to more than one of their children and these profiles were also automatically red privacy, which I can't change, nor can I do the needed merge because I am not on the trusted list for the new duplicate profiles. It has been like pulling teeth just to explain to them how to either change their own privacy back to yellow and/or restore me as a manager - some of them have still not managed to do that and without being manager, I can't change their privacy.
Anyhow, that explains why I may be listed as a second manager of profiles of some WikiTree members.
