For one thing, that's why there's more than one chat; the Creator can't boot or ban anyone they like, and make other people "Masters" to do the same things. Creators can also edit everyones comments, so it's important to pick a good one.

As for the other, same deal; there's a perfectly good chat out there, even if you have to start it yourself. You can add or not add anyone you like, and it stays there as a "conversation" so every time you return it updates what everyone said. Or you can turn off your notifications for that conversation, close it, and be done till you want to return. Who shows up, and who you call, is entirely up to you and them. Believe me, I know. If no one's interested, no one's interested, and that's that, and I still don't expect that to change if RAFO gets its own chat, but, like I say, prove me wrong.
