Upvoting allows attendees to vote for the Submitted Questions they would most like the speaker to address. This feature is similar to a ‘like’ or ‘thumbs up’, indicating to the moderator/speaker which questions the attendees would most like answered.
Please note: this feature is not the same as, or linked, to Audience Polling. This feature is only available for Submitted Questions.
