I edited the shoutbox to work if you have the portal enabled on your forum. Everything else is the same, it will just work with the portal:
<script>
var topic = TOPIC NUMBER;
var board = BOARD NUMBER;
var colimg = "http://www.smfboards.com/Themes/SMFone/images/collapse.gif"
var expimg = "http://www.smfboards.com/Themes/SMFone/images/expand.gif"
var guestview = 0;
var hideboard = 1;
var collapse = 1;
var ffopen = 1;
var ieopen = 1;
var ieforff = 1;
var smileys = 1;
var infos = [];
var infos = [""];
var ieusers = 'SHOUTBOX HERE'
smile = new Array();
smile[smile.length]=["SMILEY IMAGE URL"];
$("#bodyarea").prepend("<span id='shoutboxff'></span>")
$("#bodyarea").after("<span id='shoutboxie'></span>")
</script>
