This is attributable to having switched them from Blogs to Bulletin Boards. Blogs allow a preview of an item before it is published. We are recommending that parents use Notifications and teachers want to be sure there are no mistakes when their news stories go live and are sent to parents via notifications. Currently, even if they save Bulletin Board posts to Future, they cannot preview a story. Perhaps it is a matter of building in a Preview after having saved, in Editing mode; before clicking edit or delete, show the primary thumbnail, show the brief description, and make the Headline a link, able to expand the full story.
We have semester courses where teachers would like to view their bulletin boards before the actual start of the term. The current Preview button just displays a blank screen thereby making the teacher think they did something wrong.
