Let's See More Raised Hands...
Good questions are common in mathematics...and hopefully, some good answers exist as well. The Sci.Math FAQ Team compiled Frequently Asked Questions (and their answers) about Mathematics, with topics ranging from trivia to subjects such as Wiles recent proof of Fermat's Last Theorem.
Alex LopezOrtiz headed the Sci.Math FAQ effort, involving scientists across five countries. No new entries in the FAQ list have been made since 1997; does this mean the Sci.Math FAQ group is defunct or that no new FAQs in mathematics have arisen (a depressing thought!).
Nonetheless, the compilation is contained in a 75page FAQpdf. It can be a handy guide for mathematics teachers...and their students who hopefully are asking interesting questions.

A suggested project: Each mathematics teacher and their classes of students should yearly build a FAQ for Mathematics, which could then be used in future years. Just a thought, as it would help get students asking good questions, as long as they are willing to hang around to help find answers.
