As your live session progresses, you may find some audience members commenting and others staying quiet. To encourage your audience members to comment, consider using StreamAlive's Winning Wheel.
Winning Wheel allows you to pick a winner at random from a certain set of criteria. You can choose a winner from those who commented during a specific interaction, or based on how many times they have commented during the session.
Once you have the criteria selected, simply sit back, relax, and let the wheel do its magic. If you forget to add this feature to your Run of Show, you can find it on the presentation dashboard with the buttons on the left.
