How detailed do you get writing down the rules of your league?
Me... I just literally post a message "All scoring is final per the website" " All trades reviewed by myself or someone not involved in the trade if I am involved"
"No collusion, I will boot you out of my league and shame you in public for this"
Never had an issue in 10+ years commishing... league votes... bah... I am the law and I keep it fair, no one has questioned me on it and several leagues I have are long running.
