One more thing to think about that I brought up in the wrong thread:

Think about how you'll rule on whether moderator actions should be open to public discussion. I have been on a board for six years where we didn't discuss moderator actions - users or mods.

Doing so can be very divisive. Look at the thread here about someone being banned on an entirely different forum.

On the other hand, transparency is often a good and healthy thing too.

Maybe the compromise is somehow prohibiting extended discussions. Of course, any such discussion should never take a thread off topic.

A moderator should never be the one to initiate public discussion. In other words, I don't think a mod should tell everyone "I gave that guy a warning for that." That kind of thing should be handled on PMs. But if the user wants to air his dirty laundry, maybe he should start a thread, and only then would the mod come in and give their side of it.

With the new rules as good as they are, I don't think there'll be a lot of problems anyway, and if there are, they'll be easy to settle.
