Hidden Stories
This website contains quite a few stories that have never been published anywhere else. Some of them are easy to find, but others have been hidden. The same way some DVDs contain Easter EggsCan't see a link?, this site has some stories that you'll have to work to find.
The site is set up to hide the links until you hover over them with your mouse: as you can see from the pictures here, they're invisible until then and they don't even show up if you try highlighting the text.
There's a link hidden on this page, so why not find it for a bit of practice? Then you can take a look at the site using the buttons above.
