Can anyone add to a tree?
Can anyone add to a tree that I start, or only people I invite?
I want to start a tree for the worldwide clan of people with the surname GREEFF, and I want to link and join the research of researchers all over the world. Would I have to invite other to add to the tree, and must I give them access to the tree?
On the other hand, can any person in the world just add data to our family tree, and here I am particularly concerned with enthusiastic people who care about volume and not quality, nor accuracy.
