Once I knew how to get a message resent to someone who wasn't
subscribed to our mailing list at the time it was sent[1] so they
could join an existing thread.  I don't know how to do that with the
new mailing list software, so I'm CC'ing Mateusz so he can share his
results on-thread.  Sorry for the noise.
