RSS stands for Really Simple Syndication. In a nutshell, RSS is a new way for people who publish content online to notify people interested in that content whenever fresh content is made available.

Spellhold Studios provides a RSS feed of its forums here as well as a feed of its announcements. Spellhold Studios also mirrors The Gibberling Three's Infinity Engine Modding News, which can be read here.

You will need a news reader to see the feed. Both Mozilla Firefox and Thunderbird support RSS feeds, but there are many other applications also.

For more information on RSS, view its entry on Wikipedia or read this guide.
