The lists are so low volume that I won’t feel bad if a few people experience bounces when trying to email them. -> So yes, let’s just shut it down.
If I’m not mistaken, somebody took it upon themselves to mirror our list archives. If we can track down that service, we can just point to it rather than keep ours running.
We can keep a tarball for posterity, of course.
If you want to back up the list of subscribers, you should poke around the admin interface to see if you can do it there. Otherwise, we might be able to do a db extract.
I just didn’t reference what to do with the backups (that’s related to other questions about storing backups). The subscriber lists should be available to the outreach team probably, but we won’t likely use them after our full announcements about Discourse etc. are sent as the final mailings to the lists.
