The User Manager Panel is used to add/remove users from the database. In order to be able to actually add a user to a given role, the user must be added here first (unless using the auto generate method from within one of the wizards)
To add a new user to the database click the New button. A new entry will appear Enter new user. Replace this text with your new username. Either press enter or deselect the entry to finish and commit this user to the database. You are now able to add this user to a role within the Navagation Manager Panel by using the add user to role wizard.
To remove a user from the database select an entry and click Remove.
Note: All usernames must be unique. Additionally - you can not modify a name once it has been entered. If you made a mistake then remove the entry and then click new again.
