There is an almost perfect vacuum out there about this subject other than this one blog. There have been some strange goings on today with FamilySearch.org. For most of the day, I could not sign in at all.
I am not sure what is meant by "going live." The program is completely available as far as the features have been loaded in. I have been consistently working with the program since February. Like I have said before, if going live means something, I can't say what that might be presently.
Two indications that the program is live would be 1) a notice on FamilySearch.org or a live link to the program that did not require you to be "invited" for the link to appear on the home page and/or 2) some notice on the New.FamilySearch.org homepage of the changeover.
We'll wait and see what happens on Thursday.
