I have been researching Magento's RSS feeds and there is an attribute for new products called 'In Feed'. My understanding was that this determined whether or not the product was added to the RSS Feeds, however having enabled magento's RSS, the "In Feed" attribute seems to have no bearing over whether a product is included or not. Also the only information I can find on the "In Feed" attribute says
"Options available are Yes/No. Specifies whether you would like to include this product in your website store RSS feed."
... which I also find confusing because it mentions Feed singular however Magento provides several feeds. Can anyone shed any light on the "In Feed" attribute for me, specifically what feed it adds products to.
