There are several sections like software development, web development, etc. these sections are further divided to more specific areas like C/C++, PHP,Web Site Management etc. It is your responsibility to select the most appropriate section where you should post your question. After that if there is someone who knows the answer for your question (s)he will answer.
Read this on how to ask questions the smart way.
Also if by any chance you decide to answer someone else' question read this first. More specifically make sure that it is not answered by someone else in an earlier reply. I have seen useless replies for threads that have got much better answers by a previous reply.
