As a Moderator, you will generally create all of your Poll questions prior to your live presentation or speaking engagement. There will most likely be specific times during your presentation or speaking engagement when you will want to Poll your audience. You might not want your audience to respond to a Poll as soon as they join your session.
All new Polls that you create will be Locked by default. Locked Polls are not visible to your audience and they will not be able to respond to the Poll until you Unlock it.
To Unlock a Poll simply click on the Lock icon on the right side of the Poll.
Once you Unlock a Poll it will become visible to the audience, and they can respond to it by clicking on the Poll question.
To view the results of the Poll as a Moderator, simply click on the Poll question.
