Using webmaster tools I configured my robots.txt file to load the sitemap like this: Sitemap: http://www.mysite.com/sitemap.xml
I notice you changed the name of the sitemap generated by your plugin to: sitemap_index.xml
Does this means I have to update the robots.txt files on all my sites to get the sitemap working.
Or should I remove the sitemap from robots.txt and let your plugin handle it automatically?
Love the plugin btw.
Thanks for sharing it.
