Have you ever tried to post a message to a Mozilla discussion forum, particularly one you haven’t posted to before, and received back a “your message is held in a queue for the moderator” message?

Turns out, if you are subscribed to at least one forum in its mailing list form, you get global posting privileges to all forums via all mechanisms (mail, news or Google Groups). If you aren’t so subscribed, you have to be whitelisted by the moderator on a per-forum basis.

If this sounds good, and you are looking for a nice low-traffic list to use to get this privilege, try mozilla.announce.
