You can't work with curators... One of them plagiarized my entire tree into the "World Family Tree" and is now telling me that it cannot be "undone"... And that I should just "deal with it"...

All what is in your familytree on Geni, you are able tochange or delete, but it is necessary first telling the other user who edited wrong info why that is wrong, however publishing cat's info is so wrong then you are allowed to delete that immediately

Lol. Hmm. I guess as long as it is not messing up the tree... I would contact a curator and maybe message the in-law and explain how a family tree works.
