There is an option on Chatroll so you can't let guests chat... however... its needs my user ID and stuff so it will allow people who are registered to my site log in. The chat works great! Thats why i dont want to get rid of it. Here is the script (i think thats what it's called):
<?php
// Chatroll Single Sign-On (SSO) Parameters
$uid = 1; // Current user id
$uname = 'Mithokey'; // Current user name
$ulink = 'http://example.com/profile/test'; // Current user profile URL (leave blank for none)
$upic = ''; // Current user profile picture URL (leave blank for none)
$ismod = 1; // Is current user a moderator?
$sig = md5($uid . $uname . $ismod . '5v8gt1ccjeu870bk');
$ssoParams = '&uid=' . $uid . "&uname=" . urlencode($uname) . "&ulink=" . urlencode($ulink) . "&upic=" . urlencode($upic) . "&ismod=" . $ismod . "&sig=" . $sig;
?>
