The subject list exists and I think is configured appropriately. It is
currently unadvertised.
I am ready to advertise it and announce it.
I have both Google and Facebook OAuth2 login working and advertised
along with Persona on the login page. I have removed Yahoo from the
login page because we don't yet have DMARC mitigations and I don't want
to encourage Yahoo addresses.
Twitter OAuth2 almost works, but it doesn't return email address. Rumor
has it you can't get email from Twitter, so it can't work.
Things that need to be fixed soon in core are confirmation required for
email unsubscribe https://gitlab.com/mailman/mailman/issues/213 and
DMARC mitigations, but I think we can open it up and announce it.
If no one objects, I'll do that tomorrow.
