The nitty gritty:
We, of course, recommend you be at least vaguely familiar with what we have published in the past. Once that is out of the way, there really isn't much more we can tell you. More instructions would really only clutter this page, wouldn't it? We want stories that are what we like to call "web-friendly" meaning, shorter than about 2,000 words or so though 1,000 or less is even better.
Submit only one story at time, not more than 2,000 words (but shorter than this has a better chance, to be honest). If you're submitting short shorts (around 400 words or less), you can submit up to three stories in a single file. Multiple submissions will be deleted unread.
