What is a host-only co-organizer?
A host-only co-organizer has the same in-session tools as the scheduling organizer and can even start the webinar on the organizer's behalf (as long as they are part of the same GoTo Webinar account). However, they do not have editing permissions (e.g., they cannot change the webinar date or time) and do not have access to post-webinar reports.
To make someone a host-only co-organizer, check the Host-only box when adding a co-organizer.
Note: You can add a host-only co-organizer before the session. This cannot be done during the webinar.
