Using StackOverflow-Style Engine for my website
I want to implement the whole Question answering, tagging, suggesting, rating, badges thing that stackoverflow uses in my own website.

Is there any free or even paid engines out there that I can just set it up for my website? it doesn't have to be the exact same thing as stackoverflow but close enough.
