Hello dear WIM Cami
you can unsubscribe from any group by going to the group page and scroll down the page , you find on the right side the group name with some activities as : home matches ..... and in the botom Quit group , click on it and you unsubscribe
Click on the club link... Then on the Settings (tyre like icon on the right side of the Notes as shown below)... There you should find a Quit Club option. Hope this helps.
Oh it was already answered. Sorry. 
see it was answered but I do not see it on the homepage of the group.
Hi, I often receive invitations to join a chess club or group and sometimes I just accept without searching for the group's details and so I want to unsubscribe from some of them. How can I do that? Thanks!!!
