Q&A script like yahoo answers

hi mate,,

I am looking for a very good questions and answers script. Doing a search in google for "answers script" brings back a lot of results and the choices are a bit overwhelming. Does anyone know of a SOLID Q&A script ( like Yahoo Answers) they could recommend?

You are able to get the solution to any of your query with the help of question answer script being the most widely used PHP answer script wherein one can ask his problem and get the result accordingly.
