You will note two qualifications for using Family Tree from the document:
To use the FamilySearch Family Tree, your FamilySearch Account or LDS FamilySearch Account must be authorized. Even if you already use new.familysearch.org, your account must be authorized to use the FamilySearch Family Tree.and
The FamilySearch Family Tree is currently being tested and is not yet available to everyone who currently uses new.familysearch.org. If you do not see the FamilySearch Family Tree link, it means either that you are not authorized to use the FamilySearch Family Tree or that you have not signed in.There is nothing in this document that even alludes to a need to have access to New.FamilySearch.org as a prerequisite to using or viewing Family Tree. Subsequently, invitations to register have been sent out Family History Consultants and the unqualified document, cited above, is available to anyone registered or unresgistered, signed on or not signed on to FamilySearch.org.
I have heard several statements, both official and unofficial, sent out by FamilySearch that Family Tree will entirely replace New.FamilySearch.org by the "end of the year" 2012. If this is true, then there are many good reasons for getting as many people transitioned to Family Tree before that time as possible.
Using that invitation, I have added a number of people to Family Tree. To this point in time, I have seen nothing in print or otherwise indicating that FamilySearch does not want people to use Family Tree. EXCEPT comments from users with problems gaining access to the program. Some potential users have evidently been told by FamilySearch support personnel that "You can't get onto Family Tree unless you have been authorized for New.FamilySearch.org." This is either totally untrue, given my personal experience and that of hundreds of other users, or it is something that has been recently implemented. Why would FamilySearch do this? It makes no sense. If as Ron Tanner announced, Family Tree is open to anyone who registers, either for a FamilySearch Account or LDS Account, then why, all of a sudden tie the registration into access to New.FamilySearch.org?
In addition, I doubt that that is possible to do, after the fact, from a programming standpoint. If you have a FamilySearch account and are already on Family Tree, AND never have used New.FamilySearch.org, did you suddenly lose access?
Why would FamilySearch support staff say such a thing? Lack of training and lack of use and understanding of both programs. Simple. By the way, I have reviewed every single support note in the Help Center for FamilySearch dealing with Family Tree and find nothing even vaguely related to the issue of access.
What is wrong with Family Tree? Why are some potential users experiencing ongoing access problems? I have yet to find anyone personally that has the problem. If you are having the problem. Contact me personally in Facebook and give me an email address. I will then contact you and make arrangements to get on the phone with you and see if I can get to the bottom of the problem with access to the program.
If on the other hand, there is a real issue and you must have previously been on New.FamilySearch.org in order to gain access to Family Tree. Why not put that in the official documentation? But that would essentially limit access to Family Tree to members of the Church.
