User Configuration Notes:

Every user, logged in or not, inherits the privileges of nobody.
Any human can login as anonymous since the password is clearly displayed on the login page for them to type. The purpose of requiring anonymous to log in is to prevent access by spiders. Every logged-in user inherits the combined privileges of anonymous and nobody.
Users with privilege u inherit the combined privileges of reader, anonymous, and nobody.
Users with privilege v inherit the combined privileges of developer, anonymous, and nobody.
