The Users tab gives you a list of all User Accounts. Information on all users will be found here, the user first name, last name, user name, the groups that the user is assigned to, and the catalogs that the user has access to.
Two main functions for user management are to reset the password, and to edit the user account. In order to reset the password, click on the Reset Password for the specified user, and click OK in the confirmation popup. In order to edit a user account, click on the Edit Account button. An Edit User popup will appear, with the following options for updating or editing: First Name, Last Name, Username (Email Address), assigned user group, and the catalogs the user is able to have access to.
