This is a list of examples:
- a basic example, just showing how you can retrieve some user info
- an example with conditions, where you learn how to display things or not, according to the role of the user
- a page restricted to users, that's how we call a registered member that has correctly logged in
- a page restricted to admins, or to superadmins
- a page restricted to admins only, and only admins (not to superadmins)
