Roles, and what each one can do
Owner, admin, member and viewer.
The four
Owner — everything, including billing and closing the account. There is always at least one.
Admin — everything except billing and deleting the company.
Member — makes and edits codes, links, cards, pages and forms; reads reports.
Viewer — reads. Cannot change anything.
Removing somebody
Suspend rather than delete when somebody is leaving temporarily: it keeps what they made and stops them signing in. Deleting a person keeps their work too — a code is the company's, not the person's — but the account cannot be restored.
