• Collaboration :

  • the family tree level. Each tree you have can be configured differently.
  • the user level. You can vary what each registered user can see; whether they can edit data or not; and if you want them to be able to change configurations themselves.
  • the individual record level. You can configure webtrees to show only deceased persons data; or everyone; or hide specific individuals; even people who died recently; and much more...
