I put the chapters into the submission wizard before the 19th; sometimes a few days ahead of time, other times a week or more before. Then I set the date tab for the 19th of the month. I've discovered that when the date tab is used, the story or chapter is released to the SOL moderators about 8 pm. Then it depends on how soon the moderators, who are great at their jobs, release the chapter. It usual takes an hour or two, according to the time stamps.
Sorry for the confusion. I should have stated the chapter would drop in the evening of the 19th.
Enjoy the read, and thanks again for all the emails and support.
