Yes, PM wrote:
'Some aggregators key updates to the urls in the feed, and since page
urls don't change when there's an update, the aggregator never
notices. In these cases we have to "trick" the aggregator into seeing
a different url every time a page is updated. I think this can be done
with something like: $FeedFmt['rss']['item']['link'] =
'{$PageUrl}?when=$ItemISOTime'; '

If this works for you, can you explain how it's used?  Does this go
into local/config.php, and if so, where -- above or below the
rss-enabling code?  Once this bit is added, does the URL address of
the feed that you plug into your feed-reader need to change somehow?

Thanks!
