Yes, due to the many-to-many, the "member" property is going to
represented as a set of objects. Your __str__ definition as you have
it doesn't really make sense since it is in fact a set of objects.
Try something like:
def __str__(self):
return '%s: ' % self.title + ','.join( [ '%s %s' %
(m.first_name,m.last_name) for m in self.member.objects.all() ] )
Your thinking is correct - if it was a ForeignKey then you could
simply reference the Person properties via self.member.<property>
