You need to have a Skype Account with login details and password.
Skype installed in your device with active internet connection.
no
You need to Download and Install Skype to use it!
You need a Webcam to use Skype. Not a Original Camera!
I am pretty sure you still need to use Skype Credit.
it depends!
Usually you do not need 2 cameras. But if you want to cameras for Skype you have to use splitcamera software.
A computer, an internet connection and the skype client. Some phones can use skype instead of a computer as well. You still need the other two, however.
Skype is 100% Free to use! You don't need to pay anything!
All you need to use skype is a mic and headphones. A USB headset with mic works best. Also some laptops have mics built into the and you can use that. You can't use a phone unless it's a skype phone, which you would know if you had one.
Yes, but you need a credit card :)
Skype does not require you to have a webcam, or even a microphone. If you wish to make video calls, you do need a webcam, and to make calls you need a microphone, but you can just use the chat option if you want.
You don't need twitter but it is better to make a twitter account just before your skype account so that you can use the same name
