What does Bookmark mean?
Use the Bookmark button to save a folder or discussion you are reading that you want to keep track of. When you mark a folder or discussion, it’s saved to your Message Center. You can make a note to yourself about the bookmark and go right back to the discussion or folder. You can also delete your bookmarks here. These bookmarks don’t effect your browser bookmarks, they only modify your Message Center. To see all of your bookmarks, click the Message Center button.
