Otherwise I built mine about 4 months earlier. --=20 Efraim Flashner =D7=90=D7=A4=D7=A8=D7=99=D7=9D = =D7=A4=D7=9C=D7=A9=D7=A0=D7=A8 GPG key =3D A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted --KsX4dwHjrXa+dT/Y Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEoov0DD5VE3JmLRT3Qarn3Mo9g1EFAmCSXIIACgkQQarn3Mo9 g1HWdQ/+IOTO7HyagRxjmniO4xZoMx6XWuIBDwMK8FuF7burcOmRYIGgx77YcZp6 YUIW9uqvXMxXtkKUpYt4fnWy9Rg0zNft+Ge7AxVsKGUxT7AVH9imV2JJjRhJzChR QG41owIybuHy7A5B7EU8qoxT2XVGC0dZZLQV6/fHcYtHSZMQ8NrkFG8JVDzYfrrh vywwYtx4eYP0OTjfKQW/TMIYL2MXDYPqNePQ/K04IP7YpZN9y+xVhTBmD0IOooKa bOasr07VCEB+yXrGKeQCG7uaCS5txNiLt5vYfh1cs4ANaPNJvEnKE5/OsrmuuIuB iorV6wZN6rztaElggITYlNBBENcI1ERALf8BmCLUCp/jw/W3M6HQ9aIAqoNn4nBs iAOwjnpgGJ0hj6kpM4JVro9L4RAECIgWCz5M3y5X7o67gX2tlIf5XoQgwkDeeyuG yJzf13iqdmByRc3Vpvl5DO27h1iNIox6cfOOF5TQPekZHANj4feeYWBVl90QzDIH QgCqYCRoRWMfq1klNUIy54FMTC0TV48jcN9r7+GvJZjAwirvWUOZB+6fCfZ6qaDv 3n0NSoP+phJ31ihhENGYcIG9O/jbdHPunT/MrRT0uVf6Osry2SeidUJvjbdv9ahS bfpeKf0+f2Y6kFI23fOuhiKfgldwNHv/Q0wSlzrot/k34cAtn/k= =ex/J -----END PGP SIGNATURE----- --KsX4dwHjrXa+dT/Y--
