skype

I am sure that i have said this before, but if you have a mic and speakers on your pc, then you can make free calls using 'Skype'

The calls are free if they are only via the net, ie computer to computer. I now use it to call normal phones as well, as the rates are cheap. I call the Philippines(mobile) for 14p, or hong kong for 1p a minute.
I may sound like an advert, but the more people use it, the more people I can call.
I (and most civil servants)have been on strike today. My strike consisted of me messing about on my computer all day! Workers of the world unite!!
