create an empty private chat window

you can create an empty private chat window with another chatter using this trick. The recipient will only see an empty chat window opened without any message being received.
This trick can be done using those emote commands, which do not work if the recipient's username is not written (like slap, rose). To do the trick, just open a private chat with someone and write any of the emote commands, that doesn't work if the recipient's username is not written (Example: /slap).
Its useful if you want some one to talk first..
Some other emote commands that can be used in this trick:
(/boo), (/congrat), (/comfort), (/cmon), (/french), (/glare), (/hold), (/pinch),(/poke), (/ruffle), (/snuggle), (/slap), (/tag)
