Remember, the list software is pretty dumb but it does what it is told pretty well. So...
- It doesn't like BCC. If it sees BCC it will make me approve it, delaying your post.
- If it rejects your post, ask me about it. There's usually an easy fix. No one has kicked you out of the club.
- It doesn't like long messages or big attachments. It will also ask me to approve those, and then perversely strip them out of the message.
