Hi Jeff,
I’ve included the GNU/Mailman option below. Either is fine by me in this case where we all trust each other: Either the individual’s email address is directly exposed; OR it would force the reply to go to a PM to that person. Either way, it is a nuisance to most members of the list to receive the reply messages.
A super bonus: If the “Reply-To/From” were the sender, but a CC shows the replies+random@example.org such that if the user says “reply all”, they would hit the public topic/list (as expected in most mailing lists).
