actually, family don't even have to agree to the honour code, though they can if they want:
"Family and friends of Wiki Genealogists don't need to volunteer and sign the Honor Code.
Family Members aren't expected to contribute any serious genealogy. They get to enjoy the fruits of the tree without really helping to grow it.
Family Members are encouraged to participate on the profiles of close family members and flesh out the details of modern family history. They can help fill in the blanks, contribute to biographies, add personal memories, upload photos, etc.
Family Members need to be on the Trusted List to edit a profile. (Wiki Genealogists can edit any Open profile.)"
