Hello there, Corby. Please be informed that the Clan Master and Vice Master are the one who's responsible to sign up for next week's Clan League. Every Sunday, when there is no Clan League, try to visit your Clan League tab and you will see a check box saying "Join the next week's clan league". Failure to check the box before the start of Clan League will make your Clan not being able to participate in the week's clan league.
