Hi Victoria
I use skype and video chat to my parents, you know in Union, all the time, every couple of days, it is absolutely free!!!!!!!!!!!
Free live video chatting from NZ to Can, too cool for the grandparents.
Now if you don't have a webcam, you can use voice only, also free, no long distance charges from computer to computer, some people use a headset, I used to with my old mac but got a new one now so no need, all built in.
A friend of mine in Kingston uses a skype phone, just like a handset.
The other neat thing is my dad calls landlines in Holland with it too, from his computer, some family don't have computers and it is a fraction of what ma bell charges.
Can test your skype if you want, just pm and I will send you my skype name.
Hope this helps.
