A web feed is a data format used for serving frequently updated content to users. A content provider makes feeds available and may publish the feed link on their site. Users can subscribe to the feed using an aggregator application (also called a feed reader or a news reader) running on their computer. Some web browsers also have native options for feeds, such as Live Bookmarks in Firefox.
Wikia provides outgoing RSS and Atom feeds for some wiki pages, and wiki pages can display incoming RSS feeds from other sites.
Which Wikia pages provide feeds?
RSS and Atom feeds are available for individual articles and for certain special pages. When you visit the page in question, you can append the page's URL with ?feed=rss or ?feed=atom to access the feed URL. If the URL already has elements that use the ? and = characters, you will need to include the & character in front of the feed elements, like &?feed=rss or &?feed=atom
