You can control when your conference should be made public and when to publish your agenda using the toggles in conference settings.
To get to settings, login to your conference admin portal and go to Setup > Settings
Conference Public – When this is set to YES, your conference homepage and front end will be visible to anyone. When set to NO, this will be hidden in ‘Maintenance Mode’. This is useful when you’re busy building your event up and don’t want any early visitors to your event page.
When set to NO, you as an admin will still be able to view the front end as if it was public so you can validate its look and feel.
Agenda Published – when this is set to NO, the event agenda and personal agenda pages on the front end are not shown to the public or logged in attendees. This allows you to create and fine tune your agenda in the conference admin area before making it public to view.
Admin Email Notification – when this is set to YES, each time someone registers for your event, the admins will receive an email notifying them of the registration. In most cases we recommend that this setting is set to NO.
