Can be accessed from User Settings → Add Location on the top menu bar.
It is possible to administer multiple Wavespot instances with just one unified user account. All you need to do is choose a service plan, input the MAC ID of the Wavespot router you wish to add, and the URL of the Facebook page that the patron's are expected to 'Like'.
However, in case the other Wavespot location is already registered, then you can just input the username and password for that location, and click on Get this Location button.
