    email = models.EmailField(max_length=40, unique=True, db_index=True)
    is_business = BooleanField(default=False)

    REQUIRED_FIELDS = ['is_business']

    # This is deprecated in 1.5 but we use it to get profiles extension

    #...


class UserProfile(models.Model):
    account = models.ForeignKey(Account, related_name='user_profile')
