It's one thing to ask the person who started the league if they mind opening up the league to everyone. That's just common courtesy.
It's another thing to just join a league where there is an obvious requirement. Hard to believe anyone would check the player set of the league, the type of draft and not read the name of the league they are clicking on to join & see there is a requirement.
I have played in many leagues w/Petro and I am not adverse to playing in a league w/him. It's just funny that he would join a league w/an obvious requirement in the league name.
It would be fine with me if he had started his own league at the same time & everyone opted to join his league instead. I would have gladly taken the last spot if this one didn't fill.
