Anyone can not sign up to NEW FAMILY SEARCH FAMILY TREE. I signed for an account yesterday.
I like it a lot, because it is simular to Ancestry pedigrees, and one can also post pictures on their tree.
Best of all, I can access all of the pedigrees of others.
All you have to do, is provide a first and last name and a email address. That it.
of course a user name and password.
