OK, To remove the Parsing of URL's I think you need to remove the following from functions.php (Make sure you backup the file first, I haven't tested it and am not resposible if it goes wrong )

And remove $parseurlChecked from the template

PHP Code:

// ###################### Start checkurl #######################
function checkurl($url, $hyperlink="") {
  $righturl = $url;
  if(!preg_match("![a-z]://!si", $url)) {
    $righturl = "http://$righturl";
  }
  // remove threat of users including javascript in url
  /*$righturl = preg_replace("/javascript:/si", "java script:", $righturl);
  $righturl = preg_replace("/about:/si", "about :", $righturl);*/
  $hyperlink = iif(trim($hyperlink)=="" or $hyperlink==$url, iif(strlen($url)>55,substr($url,0,35)."...".substr($url,-15),$url) ,$hyperlink);
  return "<a href=\"$righturl\" target=\"_blank\">".str_replace('\"', '"', $hyperlink)."</a>";
}

// ###################### Start parseurl #######################
function parseurl($messagetext)
{ // the auto parser - adds [url] tags around neccessary things

  global $urlSearchArray, $urlReplaceArray, $emailSearchArray, $emailReplaceArray;

  if (!isset($urlSearchArray)) {
    $urlSearchArray = array(
      "/([^]_a-z0-9-=\"'\/])((https?|ftp|gopher|news|telnet):\/\/|www\.)([^ \r\n\(\)\^\$!`\"'\|\[\]\{\}<>]*)/si",
      "/^((https?|ftp|gopher|news|telnet):\/\/|www\.)([^ \r\n\(\)\^\$!`\"'\|\[\]\{\}<>]*)/si"
    );

    $urlReplaceArray = array(
      "\\1[url]\\2\\4[/url]",
      "[url]\\1\\3[/url]"
    );

    $emailSearchArray = array(
      "/([ \n\r\t])([_a-zA-Z0-9-]+(\.[_a-zA-Z0-9-]+)*@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*(\.[a-zA-Z]{2,4}))/si",
      "/^([_a-zA-Z0-9-]+(\.[_a-zA-Z0-9-]+)*@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*(\.[a-zA-Z]{2,4}))/si"
    );

    $emailReplaceArray = array(
      "\\1[email]\\2[/email]",
      "[email]\\0[/email]"
    );
  }

  $text = preg_replace($urlSearchArray, $urlReplaceArray, $messagetext);
  if (strpos($text, "@")) {
    $text = preg_replace($emailSearchArray, $emailReplaceArray, $text);
  }

  return $text;

} 


Let me know if that works.
