Summarize this article:

The big white space on the right part of the screen is the whiteboard.  You can use it the same way as a physical whiteboard. There are different tools - pens, eraser, laser pointer, arrow, texts, highlighter, shapes, and stamps - available for you to use during your presentation. If you’re going to use some files for your presentation, you can upload them beforehand for easier and smoother presentation. Click on File from the menu and select Import.  You are only allowed to upload and present Powerpoint, image, and PDF files. The files you uploaded will appear under the Content sub-window. If you’re going to share and distribute handouts for your presentation, you can upload them and allow your participants to download them directly from the virtual rooms.  You can upload almost any type of file to be shared with your participants. Click on View from the menu and select Handouts. The Handouts sub-window will appear, and you can see the files you’ve uploaded here. You can post a message for everyone to see in your virtual room. This can be a quote, a personal message, or your call-in conference numbers. Click on Edit from the menu and select Status Bar Message. Your message would appear on the status bar of the main window. If you played with the whiteboard from step 1 of part 2, you can easily delete all your markings with one easy step. Just click on File from the menu and select Erase Annotations. All your markings on the whiteboard would be removed. It’s better to start your presentation with a clean whiteboard.

Summary:
Use the whiteboard. Upload your presentation. Upload your handouts. Post a message. Clear the whiteboard.
