Please note: in recent versions of the Zoom desktop client (Mac/Windows/Linux), if you experience the Zoom client automatically sharing your desktop upon clicking Share Screen instead of showing screen share options as you're used to seeing, go into advanced settings and under Share Screen > When I share my screen in a meeting be sure Show all sharing options is selected.

Allow others to Share in a Session

You can easily allow other participants in your meeting to share their screen in your Zoom session. You can choose to allow only select participants to share or all participants. You can also limit screen sharing to one user at a time or multiple at once.

If you’d like to give participants screen sharing permission when hosting your next meeting, simply click the arrow to the right of the Screen Sharing icon, select Advanced Sharing Options and select All Participants

Polling with a Zoom Account

The polling feature for webinar allows you to create single choice or multiple choice polling questions for your webinars. You will be able to launch the poll during your webinar and gather the responses from your attendees. You also have the ability to download a report of polling after the webinar. Polls can also be conducted anonymously, if you do not wish to collect attendee information with the poll results.
