Registration Time Frame
This determines the time frame in which the attendees can register for your event.
This determines if you want to validate the participants' profiles before they are able to book meetings.
This feature allows you to decide which participants are able to choose which sessions during the registration process.
Tick the sessions to which a certain participant type is able to attend.
If the sessions are not selectable, it means that you haven't added them to registration. In order to do so, go to the Agenda, choose the session, click on Edit and tick Add to registration.
