I'll admit, It's gotten really messy, my own fault included. But read it several times, try to play with it, test with easier setups, like just a 2 box, you'll get it eventually. It's not quite something that can be easily explained unless one of us physically sitting next to you and walking you through it. The frustration and confusion you're facing now will only aid you later on when you turn it into experience. Took me the better part of a weekend to figure it out myself, but it's so insanely worth it imo.

Steps to follow.
1. make keymaps- one for each instance running.
2. make macros - one for each set of keymaps telling the toons who to follow and what to do
3. rule the world without a leader....

still working on #3 myself.
