Are you a php, css, sql injection expert? Are you based in a western country? I have a programmming related question for you please. Please respond.
The simple way to do it, on a forum, is to just ask the question. If you can't divulge specifics, due to NDAs or other privacy issues, make a general question, using broad strokes (not too broad, we need to know what you're asking about) - and you will probably get some answers.
@PoPSiCLe has it right -- just ask. If nothing else you'll get a whole range of responses from which you can try and glean some truth.
