RSS (Really Simple Syndication) is enabled for the home page and in the forum

The RSS icon is at the bottom left corner of the home page and the bottom right on forum pages. Click the RSS icon on any page to set up a feed for that page in your browser or feed reader.

RSS is powerful, but if you are not already using RSS feeds on other websites and you just want to subscribe to the home page, it is easier to subscribe to the home page via email than to start from scratch with RSS. If you are curious about RSS, use Google to learn more.
