@BeAware There's a third problem, which is that if the original author is *definitely* not going to add the reply to the `replies` collection, it would be nice for others to know, so they don't keep sending the same reply over and over.

The easy way to do this is to have a property that defines who is allowed to reply, like `repliesWelcomeFrom` or something. We don't have that right now, even though it's pretty widely requested.
