If you want to leave a group that you are a member of, first find three dots on the top right corner of the group homepage.
Click on the three dots. A small window will pop up. Select the text "Leave."
Click on "Leave." You will be prompted to verify that you want to leave the group. Click "OK" to leave.
Note: This applies to Action Teams, Custom Groups, and role-based groups (Group Leaders, Liaisons, etc.) If you need to change your CCL chapter, see Changing Your CCL Chapter Membership.
