Only moderators can add polls and quizzes to a vialogue.
With the "poll" feature, you can intersperse quizzes and surveys throughout your discussion to take a quick temperature of your audience.
To add a poll question, switch to “Add Poll” beneath the video player. In the same way that you added a comment, clicking into the text box will generate a timecode. Your quiz or poll question will appear in the discussion in order of its timecode.
