REMINDER: You can only leave a group if its settings allow it. If your group settings are "locked," once the first game tips off, you will NOT be able to leave your group. You can always leave a group before tipoff.
To leave a group, begin by clicking on Groups
Now click on the Group Name. This will open the Group page
Now click on the Gear icon next to the Group name. This will open the Group Details popup. To leave, click on Remove Entry. NOTE: You must select each entry to be removed in multiple-entry leagues.
