I stopped taking the quiz as soon as I realized you have to type both first and last names. Just press the type-in generator button when making the quiz and it will do it for you. Its a real downer otherwise. Good quiz idea though.
I was thinking of adding last names as a valid answer after completing a series of quizzes that would be related theme wise. I know it can be a downer when type-ins are overly strict, trust me. I simply prefer completing a quiz and modifying it afterwards rather than taking a lot of time to put it live. That way I can fix any problems as they come up. The new version should be up soon.
