How do I add teammates to my account?

Go to your avatar → Settings → Organization Settings → Organization members, then click 1 Invite Member.

Enter their email address and pick a role: Admin, Author, Reviewer, or Viewer (Owner isn't one of the invite options — it belongs to whoever created the organization). They'll show up with a 2 Pending status until they accept the emailed invitation, at which point it flips to Active.

Team seats are highlighted as part of the Enterprise plan, but the Members/invite screen itself isn't Enterprise-exclusive — check your plan's seat limits under Subscription Plans if you're not sure how many teammates you can add. See “What can each team role do?” below for what each role is actually allowed to do.
