I'm using rules, how do I get some visual feedback that an objective has been met, or it's current status.

You can also insert the 'current results' object which is in the object library. This puts a simple annotated object on the page showing the available maximum score and the current score.

You can use IF SUCCESS STATUS and/or IF COMPLETION STATUS actions attached to any suitable event to check current objective status. If condition is met, then you may display some object, or alert message or launch any other action sequence.
