The message signing feature available in the Bitcoin-Qt client lets me prove that I own a Bitcoin address. I don't wish for this address to ever be used for a future transaction however.
Is there a way I can get the private key (and address) removed from the key pool so that it will not end up being assigned when I click "New Address" or used for the change address in some future transaction?
If so, what is the command and syntax? (Presuming I do this from the debug window).
