Re: Mass email function
I have an admin interface, but it’s ugly and incomplete. I think a plugin for mass mailing your users should have an opt-out option (and opt-in at registration), which i haven’t implemented.
I don’t agree with _ck_, because a forum or a community should have a way to give important messages to its users (sometimes you can’t rely on RSS). If such functionality is not being used correctly, well, that’s another case. And i don’t think Google or another service could ban you if you present a normal usage (ie., not thousands of e-mails every minute).
