Then add this code to the place in the website that you want the blog feed to be:

<table>
<tr>
<td>
<?php

include("RSSFeedReader.php");
reader("http://www.treemetrics.com/blog/feed/rss");
echo display(10, true, true, true);

<!-- the 4 items in the display function are as follows:
10 - the number of posts to be displayed
true - the channel title will be displayed (In this case "Treemetrics Blog")
true - the post descriptions will be displayed
true - the date the post was published will be displayed
-->
?>
</td>
</tr>
</table>
