For example how about showing how a plugin would capture if someone (mod or admin) adds a picture to featured. So this would show how to capture a remote instance from a core system class.
and for a basic user show how a plugin would capture if someone adds me (admin) as a friend.
There really needs to be a clear cut and simple example of how to capture instances of an event and how to pull the data once you have the post captured via ajax. And how to test if your ajax is working or not.
