Thanks, Andy. The advice was a useful one.
I have come across Magpie < http://magpierss.sourceforge.net/ > in the past,
but it does not appear to achieve the task at hand. As I continue to explore
using search engines, I fail to find relevant scripts. I tried many
different search phrases to no avail. I could find one tool <
http://www.rssmix.com/ > that aggregates, but 'offshores' the feeds, much
like Feedburner. I'll continue searching for something I can install and use
locally...
Cheers,
Roy
