Would like a "Completed!" div to overlay page, then disappear
I'd like to give our users a "Completed!" message in a popup display once they submit a form. I want the background(e.g. the form page) to be darkened briefly (like the lightbox plugin), and then have the "Completed!" box fade away after a few seconds. Then the underlying page should be active again.
I see this on current websites all the time. I'm wondering if this is a jquery plugin?
