With Viewer Registration a user can require anyone who views the presentation to enter their Email, Name, or Company. Viewer Registration can be enabled for presentations that are published to a public link or embedded in a website. It is not available for presentations viewed offline or from an invite. Presentations viewed as part of a Meeting always require the viewer to enter their name. Viewer Registration is available to users with Trial, Pro, and Enterprise accounts.
