My company has several ecommerce sites and we have a blog that talks about them all and the latest news in our industry. We want to create a feed just for our new products in which the users can subscribe. This feed or posts wont show up on the regular blog but only in the feed if they choose to subscribe. The post Title has to link to the products page and no where on our blog.
My question is, what is the best way to go about this. I have researched on here and of course googled around a bit. I tried creating a custom RSS feed but my PHP and knowledge of template tags aren't the best. I want to be able to have this RSS feed only grab the post from the category of new products, when a site admin makes a post in this category it doesn't show on the site and the title links to that products page on the external site. I know there is that category visiblity plugin and the questions that were on that didn't fully get answered.
I have seen other sites that have their main blog feed and a new products feed, so I know its possible. Are they doing this most likely outside of wordpress on their own servers and scripts to dynamically generate these feeds and then burning them through feedburner. I saw that the one site that is doing it, the feed is just linked to the feedburner feed.
Any Help will be greatly appreciated, there isn't a lot of useful documentation on how to do complex customization of the RSS Feed templates and the use of template tags inside of them.
