Just adding, as I did in another post on this topic, that as a complete noobie, editing/revising my stuff was near impossible as I hadn't the faintest idea, other than grammar, what I was looking for. I could have read the thing 50x and still not have noticed problems.
So, for me, taking a class, like Barbara's or Holly Lisle or any other, that's structured and will walk someone through the revising process, is really, really helpful. You may not need this. I only recommend it as someone who had zero experience with the process. Conflict? Dialogue? Scene structure? Pacing? I really needed help! The online stuff allows you (depending on the class) to work at your own pace, so you can really apply (or ignore!) the material!
Anyway, as a lways, congrats on finishing and good luck, whatever process you pick!
