<snip> The location of Grimmauld place is blown, but the house 
itself is not.  In other words, the DE could go to Grimmauld Place 
and stand outside Number 12 and unless they have the Secret password,
 they will not be able to see the house, numbers 10 and 14 would 
appear next to each other.  So the Order could still technically use 
the house, but I agree with Jim in that they would be stupid to do 
so.  There is nothing to stop the DE's from staking out 
the `invisible' house, front and back, watching those who appear and 
disappear inside.  Then there is nothing to stop the DE's ambushing 
the Order members as they leave.  Grimmauld Place is no longer a Safe 
House.

LV knows of the Orders existence and though him his DE, or at least 
those DEs LV wants to know, know.  LV knew every active member of the 
Order during the first war, as Mad Eye tells us that the members were 
being picked off one by one.  It stands to reason that LV is aware of 
whom, out of the original Order are still alive, from Peter and/or 
Lucius and other informants.  LV may not know who the new members 
are, yet, but I doubt it will take him long to find out.  He will 
know through Bellatrix who was fighting for DD at the MoM battle, so 
Tonks, Shackelbolt, and Lupin along with DD and Harry are currently 
one the top of LV's Order Members That Must Die List.   I don't 
believe anyone can destroy a house that is under the Fedealius Charm 
unless they have the Secret from the secret keeper.  So, 
hypothetically, Harry could destroy Grimmauld Place but LV couldn't.

Carol:
I agree with all of this (though I thought, perhaps mistakenly, that
it was Lupin who talked about the former Order members being picked
off one by one). What I wonder is whether Narcissa could order
Kreacher to destroy Grimmauld Place from within. He would do it, IMO,
even if it meant his own death, and his one wish (to have his head
decorating the hallway) lost forever--unless, of course, he was
forbidden to do so by the portrait of Mrs. Black.

Technically, of course, Harry isn't an Order member, but that won't
matter to LV. And Bellatrix will also have given him the names of any
junior Order (DA) members she recognized--certainly Neville and
possibly Ron and Hermione, if Lucius or LV had filled her in on the
identity of Harry's best friends. Ginny Weasley would be easy to
identify, too, from her red hair and her resemblance to Ron. Luna is
probably the only one teenager present whose identity Bellatrix would
be unable to figure out.

Carol, who wonders whether LV knows (or guesses) that Snape is also in
the Order
