The Social is a very fun and interactive way to engage your attendees at your event and drive action; it can display upcoming agenda sessions, sponsors, photos, and announcements on a screen or projector, and is driven by the content found in your event.
You can set this up under Event Content > Social Wall > Social Wall Customization. Select the content you would like to appear in your slideshow and then use the link under Step 4 to share.
After the Slideshow is launched, it will update automatically so there is no reason to have to re-launch it or modify content in the EMS. After launching, you can hook your computer up to a separate screen or projector to display the contents of the slideshow to your audience. Note that new content will start appearing after 10 minutes.
