I rolled off an email to Ms. Bergman, asking if she had a Twitter account, and she was kind enough to reply. She said that account is not hers. Here's a pic of my
computer screen (the blackened out part is our emails — Lord knows no one needs anymore spam — and my name).
If anyone has any doubts they can email her via the
contact page on her site.
So, 1) that really sucks if someone's faking her on Twitter and now people are thinking poorly of her for something she didn't do

and 2) the mystery of the letter remains :fortuneteller:
