WinMessenger

Sends and receives text messages from computer to computer in real time without using dedicated servers. It works over any network protocol, and it is very easy to deploy. The program is a great alternative for the WinPopup program that comes with Windows 95/98, but is not included in Windows NT/2000/XP/Vista/7. The program supports graphical emoticons and hyperlinks. WinMessenger can be used on a Windows Terminal Server.
