Assets are pieces of content that are saved in a central location that can be used on multiple pages or in multiple sites. If the asset content is changed that change is applied to all pages using it.
To insert an asset, click the asset icon, select the asset you want to use, and click Insert. The actual asset content will not be visible while you are editing. You will be able to see it from the preview.
Some University-wide assets have already been created for you to use including university-wide touts.
