<?php

$randText = array(
 'Hi there',
 'Yo bubba',
 'I love Sirdude');

$randInd = mt_rand(0,count($randText)-1);
$theBanner = '<center><b>'.$randText[$randInd].'</b></center><br />';
echo $theBanner;
?>

Bam! <br />

just change the $randText strings.. add as many as you want and it'll rotate them in every time someone displays the forum list (cfrm) wink
