Can you do it with no camera?
You go to skype.com and register there and download the application. Then you sign in :) and you don't need a webcam or mic to use it. It can be used as just text based conversations.
I have Skype :o Just do what Joshua said and if you want we can talk? :D I notice in your name it says 'MW3' so it sounds interesting:3
you have to have a camera to be able to see people otherwise its just the voice
you just download it and no cam is needed
lol maybe :P
