If you receive email from Myra VanInwegen offering a RPi, it may be legit,
even if not from an official rpi email address. She is sending out boards
to favored developers.
By the way, please don't do as some others have done who should have
known better, referring to her as "the girl" or the minion with no fur and
opposable thumbs. Dr. WanInwegen has a bachelor's degree in math
and a PhD in computer science (1996), and I believe is the wife of a
colleague of the rpi trustees. I am told she is also not susceptible to
bribes.
