My apologies. I'm not exactly sure how the process works so perhaps I am asking my questions incorrectly. This is basically what I want to do (in PHP).
Suppose I have a website called mysite.com. On my site, I don't want to implement a blog like wordpress.org. I want to maintain a site here at wordpress.com. How do I display my posts on my site as if the blog was actually built into mysite.com; extracting only the posts. Is there a portion of the PHP code that will need to make a call to the RSS feed filtering only the desired category? I'm not exactly sure how it works.
For example, when browsing the "RSS feed for this topic" at the bottom of .this page, IE shows xml while Firefox shows it like it would in a reader. How do I get the PHP to show it like a reader?
