Post orders usually slow things down even further, in my experience, as waiting for [Player X] to post before [Player Y] can, and then [Player Z] can't post either because of that, it just causes more issues, even if it is orderly. From what I've seen, it's just better to have a policy of "Wait for everyone else to post, or at least a good number of people, before posting again, unless you are only interacting with [x] number of people, in which case you only need to wait for them.

That's just my take on it, up to Bridgeburner to make a policy or not.
