   {
       var form_=document.getElementById(form_name);
       var str='Неправильный адрес!!!';
       var text=document.getElementById("incorrect_mail");
       var email=document.forms[form_name].email;
       var reg= new RegExp("[0-9a-z_]+@[0-9a-z_^.]+\\.[a-z]{2,3}", 'i')
       if (!reg.test(email.value)) {
      email.style.backgroundColor="red";
      text.innerText=str;
      email.focus();
      return false;
       }
       else {return true;}
   }
$(function() {

    setInterval("refresh_shoutbox()", 15000);

    $("#submit").click(function() {
