Skype is fairly easy to use get yourself a decent webcam the low light & face tracking ones are the better ones, go to Skype.com and sign up give yourself a Skype name & then you can see and talk to any one as long as you have there Skype name if you don't have it I found it very difficult to track them down on Skype search, To make phone calls just click on accounts and buy some credits, haven't used the phone part of Skype so don't know the cost.
I think some lap tops have a web cam built in.
Give it a go Luci and you can spent hours shouting at a PC screen its OK at home but you get some funny looks if you try it any were else.
