Currently you have to subscribe to a "topic" to receive an instant alert about posts in a Space you subscribe to. Yet there are NO INSTRUCTIONS to the user that they have to do this. Can you make it easier for the user to understand their options regarding notification? An alum should be able to ask for an instant alert for a post to their class space like "Class of '02" and then only receive notification of a post to the "School News" space via the monthly digest. And there should be instructions on the choices. How would an alum EVER know to subscribe to a TOPIC after subscribing to a SPACE?
