I am trying to implement activity feed functionality for SharePoint sites. User should be able to follow activities (document added, delete etc.) on multiple SharePoint
sites by subscribing to it. All sites are available for all authenticated users. Users have the option of unsubscribing to it at any time. I know that I can add custom activities. The question that I have is how can I publish these events to only users who
have subscribed to the site. There are about 50K users. Does SharePoint 2010 provide any mechanism for storing who has subscribed to what site and use that to publish the events?
