Synapse Subscription Services
An important requirements for Synapse Discussion Forum is notifying users when important events happen. For example, a moderator receives notifications when someone posted a question on his/ her forum. An author receives notifications when someone answered to his/ her question.
In early discussion about notifications for Discussion Forum, we recognize that this kind of notifications is different from the Synapse Email Services that we have. In this case, users may want to subscribe to a topic or an object in Synapse and received notifications when something changed within this topic/ object. When receiving notifications about the events, user may or may not want to take any action. Users should also be able to choose the type of notifications they would like to receive, and be able to unsubscribe to a topic/ object and still receive notifications about events that happen around another topic/ object.
