\label{NavMaps_MarkPosts_Read}

The presence of a \textbf{'Mark all posts read'} link at the  
top of the navigation page indicates that at least 
one bulletin board or resource contains 'New' discussion 
posts. If your course contains folders, use 'Open All Folders'
to assist you in identifying which items contain 'New' posts. 
Speech bubbles adjacent to an item title, indicate 'New'    
posts for that item, can be removed in one of two ways:

(a) Use the \textbf{Mark all posts read} link on the course navigation
page to remove the 'New' label from \textbf{all} posts in your course, and to
remove all speech bubble icons from the navigation page with a single click.

(b) Click each speech bubble in turn to display discussion posts 
for an individual resource or bulletin board. 'New' posts within a single 
discussion cease to be 'New' when marked as read, or when displayed, 
depending on the display settings for the specific discussion. The 
speech bubble will disappear for a specific discussion when there are
no longer any 'New' posts.
