I have a doubt regarding chatter feeds on a record.
For example, if User A follows user B, and user B posts something to an object (e.g. an Invention), user A does not see it in their feed. They need to be either following the object or go to the Chatter tab and then select "All Company".
If I am user B and I want user A to participate in the discussion on a specific object, how do I notify him? Or how would I "invite" him to follow the object?
