it seems, most people wants just to write something in corrections to get points. But job needed isnt done. Instead of correct they just write an option of how theyve said inicial sentence. But they dont care very often about what idea had the author. 10 people can say 1 thought by 10 different ways. But in corrections nobody wants to hear your option. The author wants to hear if his/her way to say a sentence was good. If you say that something must be said another way you should explain why. If you dont explain it doesnt help to the author. So as a result, IMHO people @correct@ only to get points without doing any job and help. Not all sure, but most part. Hope I was pretty clear.
