Bookmarks help you keep track of your favorite content over long periods of time
You can bookmark any content in the community. When you want to look at that content again later, you can go to it quickly by clicking in the search box at the top of any page and selecting Bookmarked. You'll see a list of your recent bookmarks. Clicking Show all bookmarks at the bottom of the list lets you toggle between a complete list of Your bookmarks and All, which shows public bookmarks from everyone in the community.
To bookmark content stored inside the Mimecaster Central, navigate to the content item and click Bookmark in the right menu under Actions.
