Adding notes to an order sends out the email address of the administrator logged in. I have seperate emails for each of my admins of course, because if something is escalated to them, they should be notified at their own email. However, when responding to customers, I wouldn't want the customer to know their email, especially if the customer replies, because then it won't go into the support department, it goes to that admin's personal email... this logic doesn't make sense...
