hello, can you please tell me how to login with a new account name? Do i need to create a new account?
If you have the new account name simply backspace over any current Skype name and enter the new Skype name. That will add it to your logon choice.
If you don't have a new account name, then yes, simply create a new account by logging off any running Skype program and choosing "Create New Account".
If you need to install the Skype program, please do that from here: http://download.skype.com/SkypeSetup.exe
