Dynamic database?

Hey guys, I’m exploring my options with using technology to gather input from area teachers. More specifically, I’m gathering questions and answers, from them, for an upcoming Acalympics event. I’d like them to be able to submit their question(s) and answer(s), whereby this input is electronically subdivided into categories, questions and answers. It would allow us to cut & paste the already-organized information, therefore making the process much less laborious.

Something like a guestbook would work, but I’m hoping for something more powerful and dynamic … especially to subdivide the categories. Perhaps a dropdown allowing them to select Science, Math, etc. And then dynamic textboxes to input their question and another for their answer.

Your suggestions are much appreciated!
