First and foremost the content is first class, such an extensive library of short stories which isn't easy to find, so a big tick in the box for content. Found it hard to find much to pick at, a couple of bugs one which has been mentioned above with the download button also:
* Clicking the Menu Label highlights a letter X, don't know if that is on purpose but in my eyes that is a bug
* I'm not quite sure about the placing of the content under the menu label either, seems more like content I would expect to find in the footer of a page?
* I think the two column layout works well when reading books but on pages such as the submit story page on a PC monitor the "Comments/Copyright License" title is pushed down to the first column which makes the form a little less understandable on first glance.
* I have no idea what the text at the bottom of the submit story page means! Would anyone else?
In reply to the comments from ellescuba27, I think the logo needs to remain linking to the homepage also if someone doesn't know what an RSS feed is then why would they need to subscribe? But I second the need for a A-Z menu.
Overall 10/10 from me just a few small tweeks
