Jen:

> That doesn't answer the question of which Order member was 
supposed  to be on guard the night Harry & Co. went to the MOM.
I suppose that  Order member was attacked and removed by the 
DE's prior to Harry's  arrival. But we don't find out who it was in 
OOTP. Hmmm.

Pippin:
I don't think there's any canon that Order was still guarding 
the door, at least by the same means.
It would have been useless and dangerous since Voldemort had
become aware of the guard and how he was concealed.
