The fateful day is December 18, 2013. This is day that the new.familysearch.org website becomes read only. Here is a screenshot of the announcement:
The long awaited day will finally arrive this week. But when you get into the tangles and duplicates in FamilySearch.org Family Tree, you realize that the database is going to take a little longer to sort out. Turning off New.FamilySearch.org is a huge step, but only one step among many in overcoming the excessive burden of 150+ years of accumulated user submitted family trees.
Many of my friends are despairing that Family Tree can ever be sorted out. I think it can and will. Stay tuned for developments this week.
