CPSSubscriptions is a CPS3 product handling event subscriptions and notifications. Il provides:
A subscription, within CPSSubscriptions, can be seen as a mailing list subscription. It is usually linked to a given event and portal members or visitors can be notified when this given event occurs by either subscribing or either having roles which are setup to notify on these given events by a manager. Or still being part explicitly of the mailing list. (Manager can add explicitly email to an event.)
CPSSubscriptions can right now handle mail notifications but it could be extended to handle SMS, Jabber or other notification systems, thanks the architecture's modularity.
