A message board in the WordPress dashboard which let's different users chat with each other.
This plugin adds a new widget in your admin dashboard that let's users type messages to each other. If you have used any instant messages client before, this should be familiar already.
Tested and works fine in IE7, IE8, Safari+Chrome, FireFox, Opera & Camino. Works with a few minor bugs in IE6.
