Stories must be 3000 words or less and while this may seem short for some people, your story will be much more enjoyable to your readers if you keep it under 2000.
The most inspirational story I've seen is the one about Ezra, but Blizzard would be tooting their own horn if they put that there. I also think the long lost brothers story is pretty heartwarming, but I'm biased.
I know many of you have great stories to tell because I've read them in the comments and received them in emails. Now you have the potential to get your stories seen by a wider audience, if you like that sort of thing.
Let us know in the comments if your story gets featured on the site. Good luck!
