For embedding interactive elements, you need to use a widget called a MediaWiki. Below are the codes you need to embed a Prezi or SlideShare presentation, or YouTube video. You will enter the MediaWiki through the 'Show WikiTextEditor' (the link is right above this box). One great thing about a wiki is that you can borrow code from others. By following the 'edit' link on any page, you can go into the 'WikiTextEditor' to copy/paste the code for the page you are populating with information.
