Hi,
I can help you out here. You do not need to edit templates for this.
On the single organizer this function gets the email:
function tribe_get_organizer_email( $postId = null ) {
$postId = TribeEvents::postIdHelper( $postId );
$output = esc_html( tribe_get_event_meta( tribe_get_organizer_id( $postId ), '_OrganizerEmail', true ) );
return apply_filters( 'tribe_get_organizer_email', $output );
}
So you can use this filter
tribe_get_organizer_email
to obfuscate the organizer email.
Let me know if you have any follow up questions.
Thanks
