Allow more than yes or no answer
Allow multiple choice responses, ideally with radio button (one choice) or checkbox (multiple choice) selections.
Sorry, Yarp was designed specifically to handle just boolean choices. It is unlikely that this original premise will change anytime soon. For an alternative, with multiple choices, please try a service like http://doodle.com/
