I've started writing a quiz about famous addresses, and I have put it in the Geography Miscellany category. Is that the appropriate category? I read the guidelines, but I am still not sure. Help! And thank you in advance.

This sounds an interesting topic. However, I don't think it really counts as Georgraphy. The World category has a World Sites sub-category that has a quiz on World Addresses. Probably this is the best place for your quiz.
