I line edit and even after someone says they have had a friend who is an avid reader check their work for them, I find mistakes on nearly every page. I am shocked at times how their storys are all over the place, no continuity. I check spelling, grammar, punctuation and sensibility of the story being told. It takes alot of time and effort but when the writer gets it back he/she knows its ready for an agent or publisher. JJ, I would still attend any and all those classes you mentioned, one can never know, learn or relearn enough to be a better writer and/or editor.....
