Use the Express client

The Cornerstone Classroom Express client is a browser-based client that does not require Java plugins. The Express client is based on WebRTC standards. WebRTC is a free, open project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs.

The Express client does not provide an alternative to the Cornerstone Classroom App; however, it provides a fast and easy way to attend an event without the need to install the App.

Attention: Currently, the Express client can be launched only by participants, but not by leaders and co-presenters.

If you are using the Express client, then your name appears in an italicized font in the Attendees panel. If a leader or co-presenter right clicks a user in the Attendees panel and if the user uses an Express client, then the menu displays a title bar with the words "Express client". This allows the leader or co-presenter to know that they cannot promote the user to a co-presenter because the user is using the Express client.

If the Express client is enabled and if you are on a supported browser and are not the leader or co-presenter, and:
  • If you have the Cornerstone Classroom App installed and is the preferred client, then when you click the Attend link, the App launches.
  • If you do not have the Cornerstone Classroom app installed, then when you click the Attend link, the Express client launches.
