I had some spare time today and did some research. A plain-text 50,000 word document with minimal formatting, run through Microsoft Outlook, creates an HTML file that's almost one MB. Now, true, doing it by hand means less of Outlook's garbage, but that's still a large file. So... Bear, you were offering space, right? How much space are you offering?
Also I'm hoping to whip up a real simple "frame" for my story so that I can organize it by day and make things easier for me to publish it online; also I can add images, if I want, and table of content, etcetera. If anyone would like me to make a similar page for them, and then use it wherever you're posting your story, let me know and it up. We can even customize it to suit your story!
