Thanks @pfaffman - I see the trust level setting for emailing-in of posts.
Presumably there is a way to lock certian users who sign up to trust level 1 (say) forever, without restricting other users? So that trust level is unaffected by level of experiance for those users?
Is is possible/worth requesting that a similar email trust level setting is added to control mailing list mode via core functionality rather than relying on plugin?
I presume anyone else not wanting email in is also very likely not to want mailing list mode active, given that a mailing list mode context is the main use case for emailing in?
Hate the idea of getting a plugin made for a single trivial purpose, that likely just gets broken in some future update.
If it comes down to css, can this even be made conditional on user trust level?
I am basically trying to maintain privacy and restrict access to most topic categories to only full users, while making one topic categoriy available to the public for more casual interaction - but I still don’t want to make it easy for users of the public area to email even these discussion threads to people who are not vetted users at all, or to make record copies that do not reflect the most recent edit to a post (low but nontrivial litigation risk if a post is carelessly worded, especially if it is also disseminated beyond the forum)
