Hey Fedi,
What's a simple #mailinglist software to set up? For a low-frequency, small group, max 50 participants (parents in my kid's class)?
@zladuric
Dot com, rather.
But you said software not service so feel free to ignore. If you are stuck we can dig a bit more for you. Someone might have posted something useful that we can see.
@dsfgs thanks. Apparently they're thinking of actually doing that at the school level so iwon't have to bother. But if it doesn't workout, I'll take a second look at all your links.
Thanks again for suggestions.
@zladuric Have you already looked at Mailman? https://www.gnu.org/software/mailman/index.html
