Bizarely, the module does not create a physical file on the server, So i added this functionality.
Another problem is that it does not message the user on problems or success of the XML RSS feed creation, I added this functionality.
The module creates the xml output by calling the rss file through http, I added the functionality of creating the file at any desired folder by pressing a button, or by turning on a daemon application adjustable to create the xml feed automatically every as many hours as the user specifies.

Furthermore this module seemed like an ideal vehicle for the creation of a website xml sitemap used by google bots and others so I added this feature , and an extra button which creates the xml sitemap.

I will post the improved version if anyone wants it ..
