Documents are edited, reviewed, proofed, and proofed again.
So what am I supposed to do in the 'review' or 'proof' stage? Fix things myself? I think that serious content problems would get a 'comment' and sent back to drafts; likewise something that needs discussion.
But typos, small formatting nits, and punctuation? Easier to fix than to explain! Do I make such changes with change-tracking turned on and let the next proofer vet it?
