I know this topic is dusty, but I wanted to put my 2c in. Redistribution of stories from the site would be pretty rude w/o permission, for sure, but the OP isn't talking about that. I'm here for the same thing. I was hoping for a simple solution to put a rather long story on my Kindle. It would be nice if the site had an option to download all chapters of a story to a text file. I'm assuming from what I'm reading in this thread that option doesn't exist.
It would be nice for putting on e-readers, and it would not really cause a problem with redistribution as the text is available on the site anyway.
