axle's administrator pages allow you to add new users, adjust users' permissions, add new catalogs, add new data fields, adjust axle's appearance, and more. The initial user you created with axle is an administrator by default, and you can make any user an administrator by checking the administrator checkbox on the user page. To enter the administrator section of the user interface, click on the user button at the top right of the screen, and click the administrator pages option. If this option does not appear, then you are not logged in as a user with administrative privileges.
