From the setup area, click the "Manage submitters" link. This shows a list of the authorized users, sorted by default by the submitter's country and name.
The Status column provides a quick view of the submitter's status:
The submitter is locked.
The submitter is currently logged in.
The submitter is currently logged off.
Deleted submitters show at the bottom of the list and are greyed out.
Select the submitter you wish to edit, to continue to the submitter's detailed view. Below the user details, click on the link "Edit submitter". The form is similar to the creating new submitters form.
Please note that the "New password" fields are optional when editing a submitter, you only have to fill them in when changing the password for the submitter.
