David Deubelbeiss of English Central and EFL Classroom 2.0 recommends this quiz maker, saying it has the "most potential of any Youtube quiz maker. It has an attractive interface, is well laid out and designed and the library is very accessible. One downside - it doesn't allow you to edit the quiz after you've produced it (usually the case with just launched sites). I'm sure they'll work things out"
