What non dev-related mailing lists are you subscribed to?

I just realized maintaining a mailing list is super easy using sr.ht. E.g:

https://lists.sr.ht/~sircmpwn/free-writers-club/ https://sr.ht/~amolith/book-club/

Mailing lists feels like a minimalist and simple form of forum that immediately filters out the junk of noisy social media.

Are you subscribed to any non-dev related mailing lists?
