That's what I am looking for: some kind of quiz thing.
Something like admins posting a question, or a series of questions (not necessarly in one day!), people can answer and their answer is stored untill the answer is given. Points should be added to every quiztaker automatically.

And to make things more difficult, I also like to run multiple quizzes, with multiple scores.

I love it already :)

i thought about having the same by hacking the poll, it would be a nice idea, if someone can do it.
