Boss, I am not going to comment on asian, india, american and whatsoever.. Are you sure if some expert will explain for me then others will not read it and will not benefited from it ?? Its one own way to ask or seek cooperation from others friends(as I consider here). Everyone has some extra knowledge which you may not know. And it does not matter whether you say 'please' thank you, or give me. All depend upon how you perceive others. I thing this forum is for helping others and getting help from others.. I don't expect to say "explain me this thing and I will pay you for that . have you done so any time here ? I do never think of anything free or paid, I am here because it is good place to exchange knowledge. and Ofcourse, english is not my primary language but I am happy that I know many language.
