I created a flag called flag-follow for nodes and a rule when a user reads a node is has interest in and wants to follow the activity of this specific content. He clicks on a "Follow" button. So far, so good.
Then I created a rule, he should be notified by email when the content is updated or if a new comment related to this content is written.
Do I need to create a individual rule for each action?
Also, is it possible for a member to know which of his content is followed and by who without any custom modules, besides views?
