Didn't know about Google trivia, looks cool

I thought about the problem of people looking up the answers in Google. I was going to prevent this by allowing only 10-15 seconds to answer the question. Then again my database contains hard questions too. Some of which I don't think the average user will know the answer. I might make the allowed time per question dependant on the question. Allowing more time for harder questions. Not sure about this.
It's cool to see people sign up, do continue

Some features i plan for the future:
- Monthly rankings for most quizzes played with a price
- Monthly rankings for most correct answers with a price
- Monthly rankings for most quizzes won
- Badges & reputation
- Special themed quizzes (spanning multiple days)
