When I was in High school and college, my mother, who was a english teacher, gave me a great proof reading hint to find miss-placed and omitted words. Read the story out loud. Use your regular voice and most of the placement mistakes will become evident. You might not catch them all, but you should catch most of them.
I appreciate all the effort you authors have put in to the story writing for us. Please disregard the harsh critics and keep writing.
Thanks again for your efforts
