I've seen a few Quizilla quizzes now that do not have a submit button, nor do they seem to take off and work once all the questions have had an answer selected even if I enable javascript. Yet I see the results posted by some, so they must somehow work. As an example, here is one about Chinese symbols. While I can fill it out, I can't trigger whatever it is to make it actually work. It's not a big deal, but I'm wondering just what is going on.
