Bulletin Board

I'm trying to register at another bulletin board but it says it's not registering any new users.......Is there a way I can still send posts or register myself?? I've looked at the source and it has something about opening a cookie and looking for the username and password. Anyone know how I can do it?? Here's the code:

Code:

---

<SCRIPT LANGUAGE="JavaScript">
<!-- HIDE

var dc = document.cookie;
var testUserName = getCookie("UserName");
var testPassword = getCookie("Password");

if (document.cookie) {

        if (testUserName == null) { 
document.REPLIER.UserName.focus();
        } else {
document.REPLIER.UserName.value = getCookie("UserName");
document.REPLIER.Password.value = getCookie("Password");
document.REPLIER.ReplyMessage.focus();
        }
}  else {
document.REPLIER.UserName.focus();
}
function getCookie(name){
var cname = name + "=";             
var dc = document.cookie;
if (dc.length > 0) {             
    begin = dc.indexOf(cname);
        if (begin != -1) {         
        begin += cname.length;
                end = dc.indexOf(";", begin);
            if (end == -1) end = dc.length;
            return unescape(dc.substring(begin, end));        }
}
return null;
