Thanks to qxygene for these instructions.

1. Make a copy of the included "rss2.php" file in the main directory of the site, and call it sitemap.php.
2. Change line

   16 else $rows = 40;

   to

    else $rows = 500;

3. Now visit Google Webmaster Tools. Create a site, and add a sitemap with the address http://www.yoursiteaddress.com/sitemap.php?status=all

This is a better solution than manually generating a sitemap and uploading it, or using the included RSS feed. It will automatically update when you post a new link.
A better solution is to use the sitemap module for pligg that will generate a full sitemap index as in sitemaps.org xml format and can also ping google, yahoo and ask.com when a new story is posted.
