Not that you asked for it, but what about the following. You could obviously
throw in an actual email validation script as well. It would cut down the
number of fields on your page, and would reduce the number of people
duplicating an invalid email address by copying and pasting.

<html>
	<script>
		function checkVal(o)
		{
			if(prompt('Please re-enter your email address') !=
o.value)
			{
				alert('Your email addresses do not match');
				o.focus();
			}
		}
	</script>
	<form>
		<input type='text' onblur='checkVal(this)' />
	</form>
</html>
