Adding this code to what Page?

[bennac40]

Hi,

I would like to add this code to my forum in order to track the trafic in my website.

<script type="text/JavaScript"
src="http://rt.trafficfacts.com/tf.php?k=2797g91c6061677f1383c5095103ed32118e314be 93cah12;c=s">
</script>

Can any one tell me which page should this code be added to and where. When I used to use SMF i added it to only one page and It tracked all the traffic on every page of the forum .I would like to do the samething in vBulletin.

Thank you
