Of course, if you like a story well enough you could always just create an epub in Sigil (for your own use, not to be distributed of course!). This way, you can read the story whenever you want (and off-line too). Depending on the method you use to make the epub, typically, it can take anywhere between ten minutes and a half an hour (depending on the length of the story) to make a novel-length story (but longer for epics).
If the source is a text file, the easiest way I have found is to bring it into Libre Office, do any cleanup/changes, save it as on .odt file, then use the add-in I found to convert it to epub. For html files I use Merger #12 from softsnow.biz to turn them into one single html file, then use calibre to convert that to epub. Either way takes only about ten minutes or so. The only drawback is that sometimes calibre turns both sides justified into centered, but if it does I just go back and run it again with a left justified override.
