Thanks Craig, I see that, sorry for not being completely clear. I would like to edit the super administrator information, which does not seem to have a "hover" state that revels any edit or delete options. How is that done (when I am logged in as the super admin) from within the the tool itself?
I think the values that I want to edit are "$WAGLOBAL_Admin_Password" and "$WAGLOBAL_Admin_Username", whose values are in the database from the initial install. So, other than editing the database directly via phpMyAdmin, how can I edit these values?
Also, I notice that the login for the super admin uses a "username" while for regular users it is an email address. Seems inconsistent, especially trying to explain the logic to a client. To be clear for my clients, I have added "email address" to the login page. Any particular reason for this inconsistency?
