Hosts who have more than one account will need to disassociate the Skype ID from one account to use it in another account. 

To remove a Skype ID from the account  used previously go to Settings/My Page and scroll the bottom of the screen where you will find a Skype ID field.  Remove the Skype ID, and save your changes when you are finished. Enter the Skype ID in the account you would like to use.
