1. Run setup.php (run this file ONCE, when installing the plug-in for the first time)
 
Run the 2 files bellow whenever you want to get new topics/threads and posts on your forum (We recommend not the run the 2 files more than 4 times a day)
2. Run search.php
3. Run update.php
 
You can automatically run search.php and update.php if you setup a Cron Job. For more information on cron jobs please read http://www.webmasters-central.com/t/cron.shtml or just google the term "cron job"
