@agmoore, while I'm talking to you, I can do a fiction story and also a nonfiction story and publish them or I only have to choose one of the two categories.

You can do both :)
Try to separate publication by at least one day. Two days is better. Curators seem to like that :)

@agmoore, I thought about that, 1 to 2 days, what I wasn't sure is if I could do it. thanks for clarifying that, I already have in mind an experience I had regarding that nonfiction topic.
