It's still stated in the rules that you can't be disrespectful to other members. Once you send a PM, it is no longer yours to keep. It's out in the world and you can't get it back. It can go anywhere, including to that person. And even if it doesn't, it's not nice to use the place they go to, to insult them in whatever way. Like I said, once you see a PM, it's a few clicks to forward it. And so begins a paper trail. Also Toujours is ninja'ing me, I'm not trying to echo.
