This guy said so last May: http://tr.im/mzuv :)
Sounds like the statement is out of date (if so... can you point me to
the most up to date source on this subject?).

I've used GAE's Data Viewer where I see that multiple entries exist
with the same email address. On my dev version I can use web2py's data
viewer to see that email addresses remain unique.

I have an .insert that I don't think is throwing an exception where I
then call .update

try:
    self.db.user.insert(email=email,
                                greet=True)
    self.db.commit()
except:
    self.db(self.db.user.email==email).update(email=email,
                                                      greet=True)
    self.db.commit()

So... I was thinking that GAE wasn't throwing the exception.
And if there is a less crazy code to use to achieve this please feel
free to be blunt.
