Help me spread the word.

Everyone knows the basic short forms often used in MSN: ttyl, brb, btw, ic, ...

There's one more I want to add - so pass it on.

Background:
Some of us MSN at work. In many workplaces, instant messaging isn't encouraged (and so it shouldn't be, because it's rather disruptive to one's work -- believe me, I know. Then again, so is blogging.) So, like many of you, I've developed a keen ear for people walking my way. It quickly triggers a reflect which hits "ALT-TAB" away to a work-related window. But if you're in a conversation with someone while your boss comes by to talk to you, the last thing you want is for 4 incoming message tabs blinking away in your Start Menu bar. Quite frankly, it looks bad. So this is my solution to it.

Solution:
"DMM" or "dmm" -> Don't Message Me
What this really means is: "As of this message, don't send anything to me until I message you again. I'll explain later." In other words, "NO MESSAGES". It's usually not enough to just say "hold on" or "brb", because everyone's first reaction to that is to send a message "OKAY", which starts up a blinking message tab. No help there. When you receive a DMM/dmm message, just leave the person alone until the coast is clear. So, I want to spread this acronym into everyone's IMing dictionary. Please use it when appropriate, and please let everyone else know about it!
