Want to Pass? Gmail's a No-No for One Prof

Guess someone's not a fan of the sappy Google+ hangout commercials. That's right, we've been tipped off to a peculiar new policy being implemented by a majorly anti-Google OPIM professor. The rules detail the sins of submitting assignments from a Gmail address and the resulting punishments. Oh, the HORROR of linking your Penn account to Gmail! Hell hath no fury like an OPIM prof scorned. He's clearly either a) just really proud of you guys for getting into Wharton and wants those "wharton.upenn.edu" addresses utilized to their full potential (sigh), or b) he's got mad stock in Bing!
