What owners and editors can do
The owner controls the account. Editors edit.
Owners can do everything, including inviting and removing people, creating sites, changing the plan and billing, seeing email sign-ups and their connections, downloading the whole site, and seeing the account's sign-in history.
Editors can edit sites, pages, blog posts and page passwords, use History, publish, and leave the team.
Activity shows who did what, so you always know who changed a page.
