Which form method?

Hi i set my script up like this to register a new user:

<html>
<body bgcolor="#008CBD" font="Arial">

<?php

$register=$_REQUEST["register"];
$username=$_REQUEST["username"];
$password=$_REQUEST["password"];
$cookie=$_COOKIE["registered"];

echo "Register: " . $register . "<br>" . "Username: " . $username . "<br>" . "Password: " . $password . "<br>" . "Cookie: " . $cookie . "<br><br><br>";


if ((isset($register))&&(!isset($cookie))) { 

if (setcookie("registered","1",time()+36000)){
echo "Cookie set <br>";
$register=NULL;
}
} //if 

elseif ((!isset($cookie))&&(!isset($register))) { ?>

<center><b>REGISTER</b><br></center>
<form action="register.php" name="form" method="POST">
<input type="hidden" name="register" value="1">
Username: <input type="text" name="username"> <br>
Password: <input type="password" name="password"><br>
Re-type Password: <input type="password" name="password1"><br>
<br>
<input type="submit" value="Register"> <input type="reset" value="Reset">
</form>

<?php } //elseif

else {
echo "Already Registered";
}

?>

My problem is that when i register it sets the cookie which is good. If i refresh it again it says "Already registered" which is good.. THen if i click ERASE COOKIES in IE, and click refresh. THe cookie gets killed but when i refresh my $register still equals 1 and then it just says "cookie set" again. I dont want that to happen, i want the register screen to appear again. Is ther any method for the form method i should use instead of post to achieve this?

This example will not have a form specified, you can do that.

<?php
if (isset($submit)) {
	if (empty($username) || empty($password)) {
		header("Location: register.php?back=1");
	} else {
		setcookie('registered',1,time()+(3600),'/','',0);
		header("Location: register.php");
	}
} else
if (isset($delete)) {
	setcookie('registered','',time()-(3600),'/','',0);
	header("Location: register.php");
} else {
?>
<html>
	<body>
<?php
	if (!$HTTP_COOKIE_VARS['registered']) {
		if (isset($back) && $back == 1) { echo "Username and Password are required\n"; }
?>
FORM GOES HERE
<?php
	} else {
		echo "You have already registered<br><br><a href=\"register.php?delete=1\">Erase Cookie</a>\n";
	}
?>
	</body>
</html>
<?php
}
?>
