Forgot to document friend code...

With this recent wave of RSVP emails, a friend code was included so you could get your bestie to play with you. At the time SWIM copied this code in case their friend did not receive the email. What SWIM forgot to do after that is actually place it somewhere safe. So, as you might have guessed it is gone from their clipboard history. 

What support (if any) can be contacted to retrieve this code from the survey?

Any help suggestions are appreciated.
