Due to a very high volume of spam hitting this list in the last couple days (several hundred), I've changed the list configuration to automatically discard posts from addresses not subscribed to the list instead of holding them in the moderation queue.
If your posts aren't going through, make sure you're subscribed with the address you're posting from. (Note that you can subscribe and disable mail delivery, if you prefer reading through the archives or news gateway.)
