I have tried sending a couple of test messages using the Contact us button from my board and so far, no emails have shown up anywhere that I'm aware of. Exactly which "Administrator" account(s) are messages supposed to be sent to? Can this be changed?
Kudos to you, it's always a good thing to check these things out and test them.
The messages go to the main email that is associated with the board. In your case, the email is also associated with username dmbluke. Look up that username in your ACP to check which email he has.
