iVisit (http://www.ivisit.com) is a free program for Internet audio-, video-, and text-based chatting. I have a webcam and microphone attached to my home computer, and if anyone wishes to contact me this way, perhaps we could arrange it. If there is any interest, we might be able to start a "video chat room" for discussion of polygraph issues. My iVisit user ID is "George Maschke" (without the quotation marks).
