What information can I edit in the Contact tab?

You can edit your organization's contact details (organization name, organization email, organization phone, billing address) as well as your personal information (first name, last name, email, phone). Click "Save" after each change. 

Non-member: the Contact tab only displays the "Personal information" section (first name, last name, email, phone). Organization contact details, billing address, number of units, and the user list do not appear, as these items are tied to a membership.
