congrats on your finishing of your story, Seracen! *grins, chases crickets out with a broom* and congrats on moving on to something else. it must be a really awesome feeling to finish a story. I'm starting to think I never will. what is your next project going to be? if you don't mind saying, that is.

oh. and to the esteemed Professor... I haven't posted anything for public reading yet, but I've written some chapters for a bunch of different stories I'm working on. I try to keep them to about 6,000 words, which averages around 10-14 pages in Word, depending on how much of it is dialogue. but as someone who has been reading fanfiction a lot longer than writing it, you should really try to cut up chapters into much much much smaller chunks. this is strictly as a reader, but I (and many of my friends who I know read) don't have the time to sit and read 50 pages in one sitting, and I'd imagine it's the same for a lot of other people who are balancing work and school and family and whatever. and it's always a pain as a reader to skim through a huge document to figure out where you left off. carving a huge chapter into a bunch of much smaller ones is way friendlier to the reader.
and this is just me personally, and not speaking on behalf of friends or others, but I often won't even give a story a chance if I open it up and find that chapters are insanely long. it's often not worth the trouble of trying to read part of a chapter, come back, figure out where I left off, read more, rinse and repeat. if I have 20 minutes to read between classes or something and spend the first five minutes just trying to figure out where I stopped last time, it's a little frustrating. with chapters as large as yours, the writing would have to strike me as being extraordinary to make it worth the effort and inconvenience. I only bring it up because other people might feel the same.
and also, I am writing stories because I want to tell them and I know most fanfiction authors probably write because they have a story they want to get out too. story content should never be compromised just to pander to readers. but as far as formatting goes, I think you should almost always pander to the readers a bit. I doubt that any chapter of 40 pages could possibly be written that wouldn't have a good breaking point somewhere that you could use to start a new chapter instead, and making it reader friendly is always a good thing if you actually want readers.
