If you have all the parties open NetMeeting and you know their IP addressees, then just type them in and wait for the folks to accept the connection. Then you are set. You can also display your screen on the other parties PC's and run through applications if you wish.
Glenn have you actually done this? I have had three people in the meeting but I only see the first invite and they see me. The third is in the meeting be we don't see or hear her and she doesn't see or hear us.
Is there an option somewher that I don't know about to allow me to see and hear the third person?
