use RealName when initiating a delete for another person to second
wait at least one or two days before seconding a delete, it gives a chance for the creator to MoveItElsewhere, other people to disagree with the person initiating the delete, and perhaps time for negotiating differences, etc
if you are concerned about the delete rolling off recent changes, then it is only a small price to pay to note elsewhere to followup on the page a few days later.
if the page being deleted is very controversial, meaning strong objections by otherwise reasonable community members, then wait at least a week, or just leave it in the limbo status.
deleting pages without removing (and fixing) all BackLinks first is a serious oversight.
