I guess you can scenario writer’s can submit applications to this blog and get their blog promoted. They can also send in scenarios they’d like to see featured on the blog. I don’t know about all the details yet but I’ll look at it over the weekend [hopefully I’ll get time].
I don’t know if this helped but let me know if you have any questions :)
