In a recent thread "Paged posts on a WordPress Page": http://wordpress.org/support/topic/94838?replies=5 you helped me to prepare a custom page that lists posts which fulfill some condition (I used a custom query for that) and are paginated at the same time (I prepared my own pagination mechanism for that).
Now I need an RSS thread that lists the recent posts that appear on this page. The page address is: http://my_site/news/. I would like http://my_site/news/feed/ to be a custom RSS feed that lists the posts from this page. How do I do it? Currently http://my_site/news/feed/ causes a 404 error.
