The whole "max character cap" is a pain in the butt, yes. I hate breaking up my chapters. But as Draygen said, there are some tricks you can use to make it a little better. I throw in...

...that and the beginning and end of each of my chapters, unless the next post continues a chapter, in which case I'll put it on the top of the first post, and on the bottom of the last post that concludes the chapter. I might even change that to Dragyen's astrix, as they seem to stand out more
Another thing you can do is type a NOTE at the top of your first post asking that all responses be sent in PM to you. Most people will honor that. Also put that note at the end of each post so they stay reminded.
Most people who are avid story readers will type the OPs name in "find" and just keeping using "find next" to focus on your posts exclusively. At least that's what I do.
I sill wish they'd increase the cap. I don't even write long chapters and I still run out of room. It's annoying, to say the least. Other than that, I love the formatting and clean default look. Very easy to read imo, especially love the background for quotes.
