When you edit your webinar settings, you will now have a full-page modal with an instant preview of your webinar as you adjust your settings! This includes changes to your color scheme, logo, thumbnail, etc... Once you are in the On Air settings section, you will see three tabs - Branding, Watch Page and Registration under the settings area and a Manage Registrants section for when you have registration turned on!
