+If you were wanted to access any of the membership information from a Person 
+you would first have to query the Membership model and then you can access
+the fields related to the membership::
 
+    >>> ringos_membership = Membership.objects.get(group=beatles, person=ringo)
+    >>> ringos_membership.date_joined
+    datetime.date(1962, 8, 16)
+    >>> ringos_membership.invite_reason
+    u'Needed a new drummer.'
+
+Another way to access the same fields would be to use the reverse lookup from 
+``ringo``::
+
+    >>> ringos_membership = ringo.membership_set.get(group=beatles)
+    >>> ringos_membership.date_joined
+    datetime.date(1962, 8, 16)
+    >>> ringos_membership.invite_reason
+    u'Needed a new drummer.'
