Add a person
A username on its own becomes name@g8spaces.com. If they already sign in to another Gener8 app, they keep their password and just get G8 Anatomy access. Tell new people their password yourself; they sign in on the staff page.
Demo accounts
Trial accounts for people outside Gener8. They can try everything but change only what they make, and what they make never shows on a wall. Switched off, they can no longer change anything.
