Very nice, now I only miss to format it like the rest 
Althought, best would be if I would be able to show FPSS in frontpage, in main content area
The J1.5 changes are...
<jdoc:include type="modules" name="fpss" />
instead of
<?php mosLoadModules('fpss',-2);?>
and to add this "fpss" module position in joomla, you need to edit the XML file of your joomla's template. For example, if you're using the default "rhuk_milkyway" template, simply navigate to templates/rhuk_milkyway, edit templateDetails.xml and add the line
<position>fpss</position>
at the bottom of the "positions" block, so
<positions>
<position>breadcrumb</position>
<position>left</position>
<position>right</position>
<position>top</position>
<position>user1</position>
<position>user2</position>
<position>user3</position>
<position>user4</position>
<position>footer</position>
<position>debug</position>
<position>syndicate</position>
</positions>
will become
<positions>
<position>breadcrumb</position>
<position>left</position>
<position>right</position>
<position>top</position>
<position>user1</position>
<position>user2</position>
<position>user3</position>
<position>user4</position>
<position>footer</position>
<position>debug</position>
<position>syndicate</position>
<position>fpss</position>
</positions>
That's it! 
I am using SiteGround-15-48 template, and have frontpage slideshow set up in the center of the page using "center". I can not figure out where to insert the code mentioned herein for Joomla 1.5. This is my code:
<?php
defined( '_JEXEC' ) or die( 'Restricted access' );
JPlugin::loadLanguage( 'tpl_SG1' );
?>
