SHIFT+TAB leads to the Impulse Menus which I'm sure most every one knows...

When you click 'Friends' and double-click on a friends name, a chat box shows up, which again, i'm sure most every one knows.

However, there have been numerous complaints that I've seen in Impulse Chat (which works fine) about the messaging system being flawed.  My brother, whose comp is in the same room as me, receives my messages that I try to send to see if it works, but even he won't get it for a good 30-45 seconds.  I tried to help some one out today who was having issues, he never got a message I sent as a test.

There have also been reports that people won't be notified out of game, only in game, and that it's random, and usually ends up being way after the person sent it.

I know Stardock is probably working on this, but might I suggess a similar system to that of battle net for games like Warcraft? Where you simply can whisper a useer in and out of games?  I'm not sure if a chat box popping up in the middle of a game would be such a good thing any ways.
