In the first iteration you can only define and send out one news digest, let's say a bi-weekly news digest of all corporate communications news that is sent to all users.
This new feature would allow you to define as many different news digests as you need for different target groups. An idea could be a monthly news overview for users in middle management that contains news from upper management, or a daily complete view of all the news sent only to administrators or the head of the intranet project.
