The comments section below is a good place to let other moodlers know whether this question type was a good match for your particular task or to give hints about the best ways to use it, but it's not a good place to ask for help or report bugs because it's not integrated into the forums, where most moodle discussion takes place. Please ask questions in the quiz forum and report bugs in the bug tracker.
