I agree that people should not pre-format their manuscript before sending it to a publisher. Most publishers’ websites have different suggestions and want the manuscript left justified with the right margin unformatted and ragged so they can read it. My manuscripts have been formatted that way since I read TOR fantasy’s requirements with like an inch all the way around each page. It cannot be accepted if it does not follow the publisher’s unformatted requirements. It is so much easier just to leave it unformatted for the publisher to read it and evaluate it.
