How or where are your answers posted??????????

Answers are posted right here, after your question.  

This is a public bulletin board.  Anyone can post to any question.  It works sort of like Wikipedia - anyone can post anything they know about.  But you can't expect a fast answer.  Apparently the people who have seen your question don't know the answer, either.
