In fact it is different, in templates, I sai to make, but there it is in a file php.
// Email button
$maillink = 'mailto:?subject=' . sprintf(_MD_SF_INTARTICLE, $xoopsConfig['sitename']) . '&body=' . sprintf(_MD_SF_INTARTFOUND, $xoopsConfig['sitename']) . ': ' . $modulePath . 'faq.php?faqid=' . $faqid;
$adminLinks .= "<a href=\"" . $maillink . "\"><img src='" . $modulePath . "images/links/friend.gif' title='" . _MD_SF_MAIL . "' alt='" . _MD_SF_MAIL . "'/></a>";
$adminLinks .= " ";
I did not find the solution
