used in the way described, ie. with conjunction with a mailing list, in effect converts your forum (or part of it) to the archiver of the mailing list.
Where can I find it?
personally, i can see a problem with this way of use: while every message to the mailing list will be archived, the forum may contain some additional posts that were posted directly on the board. this way, the forum is almost, but not quite, the archive of the mailing list, which can be somewhat confusing.
Oh. I see. PHPBB doesn't have full moderation of messages. That would be essential for this. There is an Approve Post MOD in development, but that's it. We'll have to see how that develops.
