Get free Microsoft NetMeeting video chat software.

Windows XP Users
You can't download NetMeeting because it is already installed on your computer. If you try to download the older version it will not work. To start NetMeeting to the "Start" menu at the bottom left of your screen. Press it down then find something that says "Run" and choose it. A little window will pop up with a blank where you can type something. In that blank type the word "conf" without the quotes. Press "OK" then it will start NetMeeting. Now follow the directions of the NetMeeting wizard. After you are done go to the home page and begin browsing servers and calling people.
