One small privilege has been overlooked by Ancestry.com in design of the ACOM site. Deletion of entire trees is very easy and can be effected by a random click or two. Recommend that the ability to delete an entire tree be accomplished only through the owner's user id and password. That affords extra protection for the tree owner who otherwise could lose many years of work due to inattention. It also precludes those with editor privileges from making a hugely inadvertent mistake.
PRIDE rules; but, mistakes do happen and a safety switch is necessary in my opinion.
