With Uncle Ron releasing a second and even further improved version of the English league system down to tier 8, I have decided to restart using this as I had only completed one season in my first save.
Here's my setup. I've been very ambitious with this and loaded up far more than I ever have before. This is after Amaroq's description of how having playable/view only/inactive leagues work. Hopefully it won't run too slowly!
