I'm pretty sure this notice means you have to choose a quiz to be spotlighted, and not that one of your quizzes got spotlighted. But it could be the same, if you chose this quiz (or another of yours). Congrats for earning the reward, and made the good choice! ;-)
Great quiz! I don't know whether this can be fixed, but the picture of Rome seems to be flipped in the north-south direction. The Vatican and Castel Sant'Angelo are visible at the top of the picture, but at the bottom is Parco Monte Ciocci, which is further north instead of south
But how is it not featured yet? Nominated for sure!
Hoping this quiz will get the nominations it deserves ;)
