01.Insert this functions into core.php.

function trimlink($text, $length) {
    $dec = array("&", "\"", "'", "\\", '\"', "\'", "<", ">");
    $enc = array("&amp;", "&quot;", "'", "\", "&quot;", "'", "&lt;", "&gt;");
    $text = str_replace($enc, $dec, $text);
    if (strlen($text) > $length) $text = substr($text, 0, ($length-3))."...";
    $text = str_replace($dec, $enc, $text);
    return $text;
}
function hide_email($email, $title = "", $subject = "") {
    if (strpos($email, "@")) {
        $parts = explode("@", $email);
        $MailLink = "<a href='mailto:".$parts[0]."@".$parts[1];
        if ($subject != "") { $MailLink .= "?subject=".urlencode($subject); }
        $MailLink .= "'>".($title?$title:$parts[0]."@".$parts[1])."</a>";
        $MailLetters = "";
        for ($i = 0; $i < strlen($MailLink); $i++) {
            $l = substr($MailLink, $i, 1);
            if (strpos($MailLetters, $l) === false) {
                $p = rand(0, strlen($MailLetters));
                $MailLetters = substr($MailLetters, 0, $p).$l.substr($MailLetters, $p, strlen($MailLetters));
            }
        }
        $MailLettersEnc = str_replace("\\", "\\\\", $MailLetters);
        $MailLettersEnc = str_replace("\"", "\\\"", $MailLettersEnc);
        $MailIndexes = "";
        for ($i = 0; $i < strlen($MailLink); $i ++) {
            $index = strpos($MailLetters, substr($MailLink, $i, 1));
            $index += 48;
            $MailIndexes .= chr($index);
        }
        $MailIndexes = str_replace("\\", "\\\\", $MailIndexes);
        $MailIndexes = str_replace("\"", "\\\"", $MailIndexes);
        
        $res = "<script type='text/javascript'>";
        $res .= "ML=\"".str_replace("<", "xxxx", $MailLettersEnc)."\";";
        $res .= "MI=\"".str_replace("<", "xxxx", $MailIndexes)."\";";
        $res .= "ML=ML.replace(/xxxx/g, '<');";
        $res .= "MI=MI.replace(/xxxx/g, '<');";    $res .= "OT=\"\";";
        $res .= "for(j=0;j < MI.length;j++){";
        $res .= "OT+=ML.charAt(MI.charCodeAt(j)-48);";
        $res .= "}document.write(OT);";
        $res .= "</script>";
    
        return $res;
    } else {
        return $email;
    }
} 

02.Insert below lines into "function getbbcode" in core.php

$text = preg_replace('#(^|[\n ])((http|https|ftp|ftps)://[\w\#$%&~/.\-;:=,?@\[\]\(\)+]*)#sie', "'\\1<br/>External Link:<a href=\"'.trim('\\2').'\" target=\"_blank\" title=\"autolink\">'.trimlink('\\2', 20).(strlen('\\2')>30?substr('\\2', strlen('\\2')-10, strlen('\\2')):'').'</a>'", $text);
$text = preg_replace("#(^|[\n ])((www|ftp)\.[\w\#$%&~/.\-;:=,?@\[\]\(\)+]*)#sie", "'\\1<br/>External Link:<a href=\"http://'.trim('\\2').'\" target=\"_blank\" title=\"autolink\">'.trimlink('\\2', 20).(strlen('\\1')>30?substr('\\2', strlen('\\2')-10, strlen('\\2')):'').'</a>'", $text);
$text = preg_replace("#([a-z0-9&\-_.]+?)@([\w\-]+\.([\w\-\.]+\.)*[\w]+)#sie", "hide_email('\\1@\\2')", $text);
