    Another site to look at is Quextit. They have a public service but also have a "Q&A Engine" that lets you host your own Question and Answer service. Easy to integrate. You can get more info at:
    Quextit is a sponsor of Dean Kamen’s FIRST Robotics Competition and provides the Game and Technical Q&A.
