Hi gentlemike2, I was expecting you to get plenty of replies on this subject, so I held off a bit.

In all the automated stuff I've had, the IP is always randomly generated. Even the opportunist that is using what I think they call a "Privacy Browser" which hids or spoofs everything. What I have found is that by checking:- if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) $lang = $_SERVER['HTTP_ACCEPT_LANGUAGE']; else $lang = 'None'; If no language is sent, it's from an automated system, which also includes search engines. As you don't want a search engine to index a Contact Me link, this seems fine. Can anyone confirm that this is correct? Regards, Bob Exton.
