There is an incredible value to having an xml file to submit to google and yahoo in order to help guide their bots through your site.
I currently use the Joomla component XMaps to auto generate the rest of the site based on menu. By inspecting the Goobot's results of my page, though, it seems that it found the message media launch page, but for whatever reason, did not scan each lesson.
I see this possibly working in one of two ways.
1. That bible study manager generates an xml file that can be submitted to google as another site tree. This would be a simple, effective solution that would not place a dependency on any other component from an install, but also from a stability standpoint.
2. XMaps has a large collection of built in plugins that add support for other components. This feature could be submitted to XMaps for consideration of a plugin, that would further the one-stop-shop nature of that well established site map utility.
The results of this would establish a healthier standing of any of our sites with search engines, it would deepen the keyword pool that would help further all of our websites into being interactive tools for the kingdom, and it would give web admin's a better grasping of their websites statistics.
