Advisers have complete control over the content that is available on the site, including Styles, Backgrounds, and Fonts. To configure which content is available, an Adviser can go to the Configure page, then click on the tab for the content to be configured. Check the boxes for the designs you want to keep, then click Save. Only the content that you have checked will be available to use in the software.
Note that if all content is checked, then all will appear. Similarly, if no content is checked it is the same as if all content is checked, and all will appear.
