Does anyone have a Skype video account? They're free and you can call anywhere in the world. Obviously, if both people in the conversation have a webcam, you can speak "face-to-face". Both callers don't have to have a camera though. (I was just waiting for someone to give a personal review of it before I download it).
It is absolutely wonderful! I love it and use it all the time, it is also quite easy to use!
