I know that as an editor, I seldom reply to a player who has has sent a correction notice, when I am taking care of corrections for authors who have left. There is just not enough time - it is not unusual to have more than fifty corrections to take care of (I usually do it twice a week). Since I have to research all those which I do not have direct knowledge of, you can see this would take up a lot of time.
Unfortunately, we can't allow someone who is not an editor to do this, as there is a lot of judgement involved - it is very seldom just a case of correcting spelling or changing a date. When it IS a simple matter, I really want to do those myself, as a break from the tricky ones!
