The great thing about webinars is that unlike a Zoom meeting the audience only sees the panelists, in a meeting everyone is visible unless the host or participant turns off their video, this can be time consuming and difficult to manage and possibly have to deal with latecomers.
With a webinar the host and panelists are the only ones seen and they can share their screens, one at a time.
So you can send an invite out to the attendees but you need to send a separate link to the panelists which you can set up in advance. When you set up the panelists, you enter their email addresses, when you have finished setting them up, and you can have up to 50 panelists, it will automatically send them an email.
You can make changes during the webinar, if there is an attendee you want to make a panelist this can be done and also take a panelist and make them an attendee.
Here’s a video I made to show you how to set up panelists and alone make attendees panelists and panelists attendees.
