@JaredSavoie I'm actually surprised so many spelling mistakes that aren't valid words at all make it into the prepubs. I would think you could catch them pretty easily with a spell checker. Maybe they do that later in the process? I still report them myself, though. Spell-check also won't catch mispellings that change one word into another valid one.
Most of the things I point out I would label as pretty obviously problems, but sometimes I'll also point out things that are just a bit iffy or need to be double-checked for one reason or another. In general I think the more I like a series the more nitpicky I'll be, but that isn't always the case. The most nitpicky thing I point out semi-regularly (because semicolons are underappreciated) would be potential comma splices in borderline cases, although I won't go so far as to suggest a correction for those. It's more of a, "Hey, this might be a thing here. Do with this what you will if you feel the need."
