Did you know you can use your computer to talk to people? If you are a broadband user, get a microphone and you can talk to anyone anywhere in the world for free. (Make sure your computer system has speakers too!!). It's really simple, and there are several internet telephony providers. The most common one is Skype which can be downloaded by anyone anywhere in the world. Then you can talk to other users for free.
You can also use Skype to call landlines, or have a Skype In number so people can call you on your computer. If you want to know more about all of this, take a look at this page of my website. Lots more info there.
