Hi,
I tried searching for this, but I wasn't able to find anything relevant, so I'm sorry if this has been addressed before. First off, I have a Drupal 5.x site that will get the upgrade to Drupal 6, and I have book pages for different categories of audio lectures that are updated daily once new lectures are out. On the front/home page, I have a status page that I edit to show which classes/lectures have been uploaded that day. After I upload a lecture to a separate file server, I go to the drupal site and add the link, lecture title, file size, etc., to that lecture's home page. For example, say the class is "Anatomy 101", and today's lecture is on the lower limb. This is how I would format the Anatomy 101 page:

Monday, Feb. 11: Upper Limb (download), 32.9MB.
Tuesday, Feb. 12: The Brainstem (download), 58.1MB.
Wednesday, Feb. 13: Heart & Circulation (download), 27.3MB.
Thursday, Feb. 14: The Lower Limb (download), 27.3MB.

I want something that will monitor that "Anatomy 101" page and sense any updates/changes, and notify a display box that shows which lecture(s) (sometimes there are two) is/are uploaded and available for download.

Is there a module for Drupal that will monitor each one of my lecture pages, and then when I go in and edit the post to add that day's content, will automatically update a status display so I don't have to do it manually? If not, is there some placeholder code in Drupal 6 that will allow me to create a module like this, or is there a more efficient way to go about this whole process all together?

Thanks!
