The polling tool can be found on the Share Content tab under Secondary Content.

If you click on Polling, you’ll be given a simple choice of a Multiple Choice poll or a Yes / No poll. These work in pretty much the same way. Clicking on Multiple Choice gives the following options:

Write your question in the box indicated and the options you wish to offer the participants under 1 and 2. If you wish to offer more choices, simply click on Add choice and it will append another choice underneath the original two.

When you’re ready to run your poll, click the Start button at the bottom of the tab.

You can see in real-time as participants make their choices in the pop-up at the bottom of the screen. The poll can be ended at any time by clicking the stop button (square inside a circle) at the top right of this pop-up.
