We have no guidelines for story length; to my knowledge the question has never come up. In defining works by length I usually use
kat’s definitions, which hold that a short story is one up to 10,000 words long.
Forum software settings currently allow for a maximum of 20,000
characters per post. If your story exceeds this, try posting it a chapter at a time. Make sure you post them all to the same thread so that there will be as little disruption of your story as possible.
I look forward to reading your work!
