how to setup SMF Boards SSI content on my site 
Usually you can run it ON PHP and SHTML pages
PHP is the same as html pages the only differance that it ends with .php instead of .html
to have your ssi working
Rename your html page to php and add on the first line (line 1)of your page this code
<?php require('SSI.php'); ?>
Then use one of the ssi codes
<?php ssi_recentTopics(); ?> somewhere on the pages where you want to show the 8 new topics.
Others SSI codes are found here:
You are not allowed to view links. Register or Login
Note that the page which you added the code to it must be in your forum directory where the ssi.php file is found
if u want to put the page in other directory u may need to modify this bit
<?php require('forums/SSI.php'); You are not allowed to view links. Register or Login?> or to what ever form you want
