I am the commish of a keeper league and 1 owner hasn't signed in in 3 months but I can't remove him. It tells me I can't change the schedule right now.
It is against Fleaflicker's terms of service to post offensive material.
It's likely too late in the season. You're in a bunch of leagues, please link me to the one you're referring to so I can look.
It's too late in the season to remove owners. We do this to curb cheating.
