On #3 you do *not* need an unlock all players event. All players are unlocked automatically when waivers run.
I don't really have time to dig thru the other questions but just noticed this one.
Based on what? His settings only call for FCFS for unlocked players but nothing actually unlocks them.
He runs waivers at Wed 11. That unlocks all players which starts up FCFS.
I see now, I'll have to revisit my league that does this, that's not how it's set up.
