The Google XML Sitemaps plugin will create a Google sitemaps compliant XML-Sitemap of your WordPress blog. It supports all of the WordPress generated pages as well as custom ones. Each time you edit or create a post, your sitemap is updated and all major search engines that support the sitemap protocol, like ASK.com, Google, MSN Search and YAHOO, are notified about the update.

Thanks so much for the sitemap info. Just finished putting it on my blog. It was painless. I was a bit clueless, but pushed all the right buttons for the most part.
No problem! This plugin is a must for WordPress! Easy to install and definitely worth it.
