If you do not want to include the time in the presentation where you had a question, clear the Time check box. To send your question, click Ask Question. Click the Share Presentation button to send authorized users an e-mail invitation with a link to view the presentation. If you want your invitees to begin watching the presentation at specific time, check the Start Time check box in the email form and enter the time.

Enter the destination e-mail addresses and update the invitation text as needed. Click Send Invite. If you want to use the e-mail client on your machine to send out an invitation, click Use Email Client when the email form appears.

8 | Use the seek bar to navigate through the presentation quickly. When you hold your mouse over a specific time using the seek bar button, the slide image for that time is displayed over the presentation.

Notes: If the video for the presentation does not appear, verify the presentation is not an audio-only presentation and that your computer meets the requirements listed here. When you are viewing a live presentation, you cannot pause, skip back, or seek within the presentation. When a presentation is live, the live presentation indicator is shown. There is only one audio stream associated with each presentation, so changing the primary content displayed does not change the audio. Interactive features (polls, asking questions, and sharing a presentation via email) are not available in stand-alone (publish to go) presentations. Top
