Changing the purpose of your organization is accomplished by changing the purpose of your largest circle.
- First, navigate to the circle page for the largest circle. (You can get there by clicking on the circle's name in the organization chart.)
- Once you're on the circle page, look for a "gear" icon following the circle name. (See the red arrow in the screenshot below, pointing at the gear icon.)
- The gear icon will only be visible if you are the Lead Link of the circle, or the Secretary of the circle, or an Admin.
- Once you click the gear icon, a dialogue will pop up that will let you add or update the purpose of your organization.
(Please note that the above screenshot is taken from a premium organization. A free organization will have fewer options available, but in either case you will be able to change your organization's purpose.)
