Thanks again Rick for the link to the Tips&Tricks file.
BTW, I changed the code from your example a bit. This
adjustment replaces ampersands in titles/url so that these are
parsed correctly by email client:
function mailink()
{
document.write('<p><A
HREF="mailto:support@company.com?Subject=');
// var temp = document.title; *//
var temp = document.URL;
// uncomment the line above and comment the line above it
using // to switch to URL. *//
temp = temp.replace(/&/g,'%26');
temp = temp.replace(/&/g,'%26');
document.write(temp);
document.write('&body=Please do not alter the Subject
line. It is used to help us identify the page you are
reporting.">Feedback</A></p>')
}
