You have heard about multi-yahoo and multi-msn but haven’t heard about using multiple Skype accounts on a single computer. Skype has given this facility and its great because sometimes you need to use more than one accounts on a single computer for multiple communications at the same time. This is valid for 4.0 version and later

In order to use more than one account on the same computer at the same time you need to start a new instance. Many people will think that its very easy to go and search for installed Skype and press the button or double click with this mouse. Here comes the tricky part and that is given as under:

1. From the Windows taskbar, click Start > Run (or press the Windows and R keys on your keyboard at the same time) 
2. In the Run window, enter the following command (include the quotes) and press OK
3. "C:Program FilesSkypePhoneSkype.exe" /secondary

If you get any error messages, please copy and paste the exact command from this post and try again. You may can get this error if you have changed the installation directory at the installation time.
