I got exactly the same email as you Josie the other week from one of my friends. I never bothered forwarding it on to anyone, because every summer i get that same email.
Wonder if its someones way of getting a big bunch of peoples emails to send them unrelated CRAP!!!!!
Becareful with them things as i did actually go onto MSN website itself to check the validity of the email and low and behold NOTHING!!!!!
So i have even double checked on their actual website and they dont even mention anything about it whatsoever!!!!!!!!
