I dabble in proofreading for fellow authors. When I read a book (for fun), I would notice, no matter how big the author was, there was always a mistake or typo somewhere. We are all human and miss even the simplest of things. I ended up making it a game and started highlighting all the typos. It's almost become an obsession, okay I'm mildly OCD.
I'm not an editor, by any means, but I like to think I am good at proofreading. I pick out the little things... missing words, misspelled words, misused words, some comma issues, discrepancies, if any; anything that may pop out to a reader.
