(Though in this case it wouldn't have helped me) I see the clear advantages this has over "just guessing" wether an annoucement might be right or wrong - but there are also some risks due to possible misconfiguration if it's only used by a minority.. Well, as you stated: it's complicated but I'm willing to adopt new and reasonable things like this. best regards Michael -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlBQ55sACgkQaWRHV2kMuAJRXACfVCVD/oTPvNHgim228btUkwTQ kvgAnjYAcmif439HdLcdQJO96NvDqukS =Rwcp -----END PGP SIGNATURE-----
