News items added to this area will be shown in the website header news bar. Do not add news items directly to this category, instead create a news item in one of the publically accessible news areas, and then use the location tool of the CMS admin panel to add it to the news bar.
The locations tool allows you to set a news item to be displayed in multiple news categories. Check the 'Header News Feed' tickbox, to tell that item to appear in the urgent news bar. To remove items from the urgent news, use the location tool to uncheck the 'Header News Feed' category.
