Do not remove Approval when Poked (both individual Pokes and via Poke Everyone)

MrDubya sure but "Email Everyone" won't change the "Waiting" statuses of users to "Active", so your suggested alternative is not a full solution; I concur with you on "changes their status back to active, which is a useful feature to bring someone back into the review" because, for example, that makes the review show near the top of their list of reviews (with a red up arrow instead of near the bottom with a yellow down arrow) and so on - which is better than simply getting only an email notification.
