When the video with Rory explaining the financial agreement guy didn't initially load, I took a look at their script: "view-source:https://bnotifi.com/ajax2.php"
For that script, in addition to that list, nFusz also used AJAX which allows page updating with reloading and sending/received data to server, XML, jQuery, PHP and I believe there were at least two coders making that script because there were two different begin end blocks styles used.
