This is an optional page I like to provide for my authors. This page is a summation of errors and victories within a work. All authors have a pattern of speech and writing, it's very common to have a reoccurring error. I use the editor's page to highlight frequent errors, frequent places of overuse or under explanation, and also places where you should build onto them. My author's have found this feedback helpful and enlightening, a mini beta read if you will.
