TOPIC: Admin Email Address

I set up events in DT Register for my client, using my own email address as the Admin email so I could test things. Now we are live and I'd like to change the admin email so notifications go to his email address.

I see the Admin Email column in the back-end Event List, but no way to change it. I have changed the email address associated with the Super Admin in the Joomla global user configuration but the old email seems locked into DT Register.

Thanks in advance.
