Thanks for the answer. I agree that there are additional uses for this functionality. I'd imagine that as people work with users posting collaborative content, this feature would come in handy. In this way, the originating authors do not have their name attached to an end product they cannot fully take credit for. This is especially true in an editor and author framework where the editor makes changes the author does not like. In this way the author is not held solely responsible for what the editor says.
