Hi Guys i am exploring a feature in my site that allows users to add questions like you would do in Quora and then other users can answer and vote (up/down) for the best answer This site seem to have done it very well.. http://www.notgoingtouni.co.uk/advice-centre advised appreciated
Being as it is a Q and A site, perhaps you should post a question to see if they are willing to share the code with you or sell you a license to use it. Otherwise if you cannot develop your own code based on the little you can see; you probably need to hire a web developer to build the site for you.
You can use the following open source PHP script: http://www.question2answer.org/ Run it on a sub domain or something.
