The Jen story was planned to appear just after 8:00 p.m. on Thursdays. Chapter 2 appeared early today. That was because I was too slow posting it.
The original story was a single long piece on ASSTR. I cut it into chapters, but I didn't get those chapters into postable shape. I did for the first chapter, and I posted it. Authors can't put later chapters into the posting queue until after the first chapter appears. So, I delayed doing the final pre-posting work on Jen. And delayed, and delayed.
Wednesday, as I was finishing me session on the Internet from the library, I realized that I still hadn't done that. So I did it this morning. Authors can't put something into time-delay for the same day, so it went up soon after I had put it into the queue.
So, my delay led to an early posting.
