After a lot of head scratching 'n searching it looks like it *was* easy enough to change the feed URL for WP1.5 from http://site.com/feed to http://site.com/xml/rss.xml
This plugin, for example: http://boren.nu/archives/2005/03/29/feed-director-plugin/
'Owever, as far as I've been able to find out this is simple job for WP2.0 (http://wordpress.org/support/topic/51409?replies=7) and with the exceptionally limited rewrite knowledge I have I'm in a bit of a pickle trying to export a whopping Manila site (top 500 Feedster one!) as the admin wants to keep the existing feed URL (for good reason!)
So, is there a straightforward way in which I could hack / change http://site.com/feed to http://site.com/xml/rss.xml ?
Am pretty much at my wits end trying to figure this one out so thanks v.v.v.v.v. much for your time.
Cheers, James
