That's fantastic, Miles! Congrats. What a huge accomplishment. I did NaNo once, and it was a great experience. As you know, I'm the fiction editor at a literary magazine, and deal with all the short fiction. I've also gone halfway on my ed's certificate at SFU (I love everything to do with words, but tables of contents and footnotes are NOT for me), and have learned multiple editors are often used for an MS. But sometimes the right ed can do it all. At the mag, we mostly take stories that are ready. Occasionally we'll work with an author who is close, but the story is too good to pass up and I see the potential fix. If the author is ready and willing to work together, I'll do a substantive edit, looking at story, pacing: all the fun stuff. When that's ready, we hand it off to our brilliant long-time copy editor. She'll find all those pesky, well-hidden grammar, spelling, usage mistakes, fact-checking—and more. Interestingly, she doesn't like the creative. She's an absolute gem. Six years at the mag, two at the Manitoba Writers' Guild, I can tell you, many, MANY people are looking for the editor who does it all. And it has to be the right fit of editor. As for me, as I'm working on screenplay right now, because of my years in theatre, when I have what I think is a good draft, I order food and drink, and invite a house full of actors to do a read. I know some smarties, and they give the most incisive crit. After the next draft, I hire fancy script ed's for coverage. Between the two, I've brought my current screenplay to it's best form yet. It takes a village.
