With the White Label license, you can basically sell Run A Webinar to others.
The way this works is, once you login to the dashboard you will see 2 options on your left sidebar. One will be users and other one will be White Label Settings.
First go to settings and you can change the logo of dashboard and login page. Once you do that, you can then setup PayPal through which you can sell the accounts.
To setup PayPal, just go to PayPal developer console located HERE and grab the APIi client id and secret key and paste it in settings page.
Once you do that, enter the price you would like to sell it to and then hit "save." You will then see a PayPal button embed code which you can add in any of your sales page where you are trying to sell this software.
Also, you can add users manually via Users tab and the login URL for each of your users you create is also located in settings tab at top which you can send users too.
