I really enjoyed this 8.5-minute video on the calling of the first sister missionaries in this dispensation:

If you’re a returned sister missionary, or a current one, or a prospective one, or the mother of one; or if you’re the sister or father or brother or son of one; or if you know or knew one; or you care about missionary work; or you are a member of the Church; or you are interested in the Church, I think you’ll enjoy it, too.
