If you are using the RSS feed for the site you may have noticed that you miss a lot of articles. That is because, for some odd reason, the RSS feed limits itself to five posts.
If you want more you need to modify the RSS URL so that it has the limit keyword in it.
So to get it to show the last 40 posts the URL would actually be
http://leadadventureforum.com/index.php?type=rss;action=.xml;limit=40;
