our previous site administrator passed away. How do I remove his email contact address from the "Email The Class" page?

I have:

Removed his primary email address from his profile
(this is a different email address than the one that
appears on the "Email the Class" page.

I removed Him from the "Contact US" page.

I unchecked him from the "Grant Admin Access" box

Sorry to hear of your loss. I believe what you are looking for will be found in the EMAIL ADDRESS AND SENDER NAME section on the Preferences page. Be sure to save changes at the bottom of the page after you make your changes.
