Sometimes you may feel like you just aren't interested in being in a particular group anymore. If that's the case, you can leave it at any time. To do so, simply go to your Groups section, click on the group you would like to leave, and click the Leave Group button on the right of the page.
If the owner leaves the group, then any group member with Builders Club can claim ownership. If there are no other members with Builders Club at that time, then the group will remain without an owner.
