You used to be able to post as many stories as you like provided you follow the unwritten rule "No more than a post a day".  We'll now I've enforced this unwritten rule in Photographica itself.

From now on, you cannot publish more than one story in a 24 hour period.  That means if you posted a story this morning at 10am PDT, you will not be able to post again until 10am tomorrow. During this time, you can create a draft of your story; you just will not be able to publish it until tomorrow.

Let me know if you have any questions about this new policy.
