http://wikitree.sdms.si/default.htm is the link to wikitree+ It WILL immediately error, just hit ok.
Chose reports/ ancestors and put your wiki-ID in there. Then hit Ancestor summary. It gathers the report by looking at you and listed parents. Then it goes to the parents and looks at their parents.
Very important is it uses the PUBLIC view. So if your parents are unlisted they will not show on yours. Then it can no longer count any higher in that branch.
If they are private, it can see them on yours but it can't see the parents on THEIR tree so it ends with THEM.
In order for it to work correctly, it must be a minimum of "private with public family tree". In cases where the person is still alive, they must sign in and claim their profile. You may still be a second PM on it though.
(stephanie, this is mostly for those not knowing where the report is)
