I am attempting to use MSN Messenger for a video call (ala Skype) for educational purposes. That is, I'm trying to learn how to do it so I can teach others. Unfortunately, I cannot seem to locate any instructions on setting up the video portion. I have been able to create an account in Messenger, but I do not find any instructions for setting up and testing the video portion (webcam). Any help would be appreciated.

OK...I guess I needed more time just playing with it! Found out that Messenger is incompatible from XP to Vista (it appears that sender and receiver must be on the same operating system). Forgive the naivete...I'm just learning about Messenger.
