the little shadow that runs through the grass

It's a community Blog for neibwes, Mahabub bhai. So please try to elaborate a little more. That way every newbie will be benefited. And bro please try to do it in a single post. You know neibwes like me always loose patience very fast. If our primary goal is to make them motivated and skilled then either there should be some good and complete post or I would prefer nothing at all. Hope you take this positively.
