making your blog private, i need helppppp. Options

[bel_oubli]

ok, i found a few codes for private blogging, and tried to combine them. i was trying to make a code that would ask you for a password if you were not on a list of users allowed in the blog. the problem is, the stupid code asks everyone for the password, whether they're on the list of accepted users or not. can anyone help me??? i'm thinking one of the problems might be that i have too many usernames that i want to be accepted. agh, help! (and i'm a newbie, so i'm extremely ignorant when it comes to html..)

my code is as follows.

<script>

var allowed = new Array(
"username1",
"username2",
"username3",
"username4",
"username5",
"username6",
"username7",
"username8",
"username9",
"username10",
"username11",
"username12",
"username13",
"username14",
"username15",
"username16",
"username17",
"username18",
"username19",
"username20",
"username21",
"username22",
"username23"
)

var links = document.getElementsByTagName('a');
name="";

for(i=0;i<links.length;i++)
{
if(links[i].innerText.match(/xanga/i) && links[i+2].innerText.match(/sign out/i)){
i++;
if(links[i].href.match('/private/home.aspx') || links[i].innerText.match('join')){
name = links[i].innerText.toLowerCase();
break;
} 
}
}
enter=false;

for(j=0;j<allowed.length;j++)
{
users = allowed[j];
if(users.indexOf(name)==0 && users.length==name.length){
enter=true;
break;
}
}

if(enter!=true){
<!--hide
var password;
var pass1="PASSWORD HERE";

password=prompt('enter password.',' ');
if (password==pass1)
alert('correct password');
else
{
window.location="www.xanga.com";
}
//-->
}
</script>
