I second this. I don't remember ever seeing Bosporus spelled with an h, so didn't think to try adding one. In addition to Bosporus I also tried Istanbul; both are mentioned in the wikipedia article as common names for the strait.
Something i noticed is the quiz screen.. kinda intersects into the right side, covering some writing. I'm not sure if anyone else has this problem or my laptop is crap.

But I liked how you used the magnifying glasses, can I use them to for some of my quizzes? Thanks a lot
