[David L.]

It would be considerate of those posting on any site, not to duplicate their question, same day, practically same time, (as we've recently become aware) on two or more sites. Some requests for help can take a substantial amount of time to answer, particularly proofreading of long essays, and if other native speakers are responding to the same question on another site, it leads to a sense of, 'I've wasted my time', and more of a reluctance to do so in future!
