For the one that did not know (is that possible?):

What is Skype?

Skype is the next phenomenon from the people who brought you KaZaA. Just like KaZaA, Skype uses P2P (peer-to-peer) technology to connect you to other users – not to share files this time, but to talk and chat with your friends.

The technology is extremely advanced – but super simple to use… You’ll be making free phone calls to your friends in no time!
