So, to put it in a nutshell, the rule is no laughing in church!. With all respect to Clint, chat isn't an alternative to writing; if you want to make a considered response to something you might have to think about it for a while. It's a different kind of communication altogether. I still get the feeling that this is more about bandwidth control than what's appropriate or not on forums, otherwise the concern would only be to (legitimately) limit nastiness rather than to stop folks joking around in general. m.
