do not show "last edited by:" tagline when moderator edits ..

How can I make it so a thread does not show "last edited by:name_of_moderator" after a moderator goes in to tweak a post?

found the answer under user group options - duh

Yeap, now also make sure they don't belong to any groups that might have this set to yes, and also be aware its not retroactive.
