Google sitemap generator plugin
A plugin for Wordpress (v2) that helps you automatically build sitemap files for google so that you can index your site almost on-demand.
This plugin generates a Google Sitemaps compliant sitemap of your WordPress blog. The Google sitemaps program is part of the “Google webmaster tools”.
I continue to be impressed by the variety of plugins available for WordPress. Not just that, but I have not had a problem with any of them at this point. All have been solid, reliable little chunks of code that get the job done.
