RE: No longer supporting mailing lists: This project literally cannot function without mailing lists. We do not currently have a viable alternative. See all of the issues we've had trying to work with Mailing List mode on Discourse. It is not a complete feature, so we (at least I) cannot recommend switching to it at this time.
Have you ever encountered the daily message limit? It seems to be quite low, at 100. That alone seems to make mailing list mode useless.
Anyway, I thought this is about switching to external hosting of mailing lists for those who need them, not banning them altogether.
Thanks, Florian
