I think it was mentioned last month how people sometimes tried to do clever things with their stories, Mouse's mouse shaped story springs to mind, but there were were palindromes, acrostics, puns (okay, Ursa still does them), word play and goodness knows what else.
It was fairly customary for the writer to just let known there might be something hidden away in their tale.
Having had a little chat with one of the mods, it should be all right for me to say the following.
We thought I'd leave my entry and not say anything, just see if anyone noticed, then mention it later. (All I know is one person did). I thought I'd wait until the tenth of the month or until I hit the 5,000 post mark as they have coincided:
There is something hidden away in my story.
In fact there are could be as many as six, possibly seven somethings hidden away in it....
