Decide to share my own code that put Tag Board into Ajax window.
So what you should do ... 1. Find a place where to paste code below
Code
<?if($USERS_ON$)?><?if($USER_LOGGED_IN$)?><a href="javascript://" onclick="openLayerB('ID',0,'http://udev.ucoz.net/mchat.xml','Tag board',300,400,'1','','',0,'justify'); return false;">Tag board</a><?endif?><?endif?>
It make link to your Tag Board. 2. Upload file mchat.xml from Attachment to your site.
3. Enjoy new style & functionality of your Tag board
