I would love a Quiz feature. Tightly integrated like the Polls are. A great way to build community, share knowledge, generate discussions on how each member did, the questions, prizes, contests, and much much more.
I think it's a space that has been largely neglected by the developer community <img src="https://www.ubbcentral.com/boards/images/graemlins/laugh.gif" alt="" />
Thoughts?
