:-) Hey you...yep who else would be asking such a question...
I tried to remove the Sun subscription, then the feed did not validate because of a google aggregated post...
I guess it's never ending.
Customizing feedWP is way beyong my poor knowledge.
But what I don't get is that I was able to aggregate those feeds and they validated, so the least the could do would be to validate also when I need an RSS feed, don't you think?
Plus I spend my time sending emails alerting people that their RSS feed doesn't exist/doesn't work/doesn't validate/is nowhere to be found. They are able to fix it, but I doubt that Sun would do anything for me nor Google...
