[Please Note: There are quite a few valuable comments to this post. You should take some time to read them.]
Today, 24 March 2016, a massive number of duplicate child to sealing green Temple icons showed up on the FamilySearch.org Family Tree. These are almost uniformly duplicate ordinance "opportunities" that are for children who died young and were "born in the covenant." This is one of the strangest duplications that have occurred so far with the Family Tree. I suggest that those who recognize that these children do not need duplicate ordinances quickly reserve the ordinance of sealing so the sealings are not done for those who do not legitimately need them.
You might was to pass this along to any interested members.
