Crawler is a server-side application which automatically crawl sites your users subscribed and store their feeds in the server strage routinely.
With the crawler, you can get the very latest feeds every time you access to the Fresh Reader without 'Check for the update' button.
You can see the explanation of how to set up the crawler on your server by clicking [System Setting] >> 'Crawler Setting'.
If you are using Window2000, see Run Crawler on Windows2000.
If the crawler does not work, please run crawler.php from the command line interface and check the messages.
You may need to change current directory to which crawler.php exists.
