Unfortunately 87all(_at_)ietf(_dot_)org --the "announce" version of the
list-- is where the really important things, like schedule
changes, show up. And, at least as far as I can tell, there is
no way for a non-registrant to get on that list.
Has anyone tried to subscribe on the listinfo page?:
https://www.ietf.org/mailman/listinfo/87all
I just did, using another email address, and that email address got
the normal "click here to confirm" response.
