I'd be curious to get the information—and if you don't have it at this moment, the committee can receive it at a later time—on the number of applications that are still outstanding, that need to apply, because I think there's a difference between that number and the 1,000 people that have not yet made contact.
Following that, once the letter has gone out to those individuals, presumably, if they're no longer at their current address, the letter would be returned to you, and you would then be tracking how many people you have lost contact with.
Are you able to provide that information to the committee then, to let us know how many letters were returned—that is to say how many people you were not able to make contact with?
