https://lists.wikimedia.org/postorius/lists/wikifr-l.lists.wikimedia.org/ has been inactive since years.
The French speaking community has the IRC channel and now even a Discord channel https://fr.wikipedia.org/wiki/Aide:Discord. I believe this is mostly the reason why the ML is dead.
Now we have with @PBradley-WMF to deal with a request to remove/hide 10 years old emails which disclose private information.
On the top of this, as owner of ML, my password somehow does not work and the reminder password solution fails to deliver a new one.
So all-in-one, just archiving and making the ML private might be the best thing to do. This is why I request it.
