Authors in the moderation queue: When submitting a new story to the site, do NOT post more than the first chapter, or prologue and the first chapter. Additionally, while you remain in the moderation queue, do not post more than one new chapter or new story until the existing chapter/story is approved. The moderation queue is typically reviewed once per day. Do not use the post-dating system while you remain in the moderation queue.
All other authors: When submitting a new story to the site, do NOT post more than the first chapter, or prologue and the first chapter. Two new chapter or story updates can be posted per day, total, and spaced at least eight hours apart. Chapters submitted using the post-dating system do not count as long as they're evenly spaced per the rules.
Why the limitation you ask?
We want our site's visitors to have a chance to read or sample a variety of works submitted each day by our authors. When authors submit too many stories or chapters at once these other works are sometimes lost in the process. We've found stories posted over longer periods of time attract more attention and therefore readers. Not every reader visits daily, so they are more likely to give your story a chance if each time they visit they see a new chapter in the list of recent story updates. Spacing out submissions is a win/win for both your work and your fellow authors' work.
