We normally use more than one services for only purpose. In the same way, we tend to register a couple of accounts at one service provider but only use one or two of them. For instance, I use both Gmail and Yahoo Mail for exchanging with friend or receiving mail, notification, receipt etc… from online services. Obviously, like many other users, I register more than one account at these popular email services. They are completely free, we all know!In case of Skype, it is the same. In fact, it is quite convenient to own and use multiple account for different purposes. You can easily interact with your colleagues to exchange about the current projects via first account, meanwhile using the second for calling, chatting with your partner, friend or family. So, we sometime may look for a solution to run or open multiple Skype accounts at the same time.
