popup-ing a window

[??????]

hi, :)

where can I put this code


<SCRIPT TYPE="text/javascript">
<!--
var answer = confirm ("hello, you are not a member, do u want to register?")
if (answer)
window.open("http://www.mywebsite.com/vb/register.php?action=signup")
else
alert ("have fun")
// -->
</SCRIPT>


and what templates to modify so that when someone visits my website, a messagebox is shown as above.
