I don't know much about RSS feeds.  Can you help me understand how they work?

Clicking on the RSS icon allows you to set up an e-mail feed so that new content on that area of the site is delivered to you via e-mail.  

Whenever an RSS icon is present on a page, it represents an RSS feed for only the dynamic (changing) content on that page.  If content on the given page is "static" by nature, it will not be carried along as part of the feed. 

Here are a few examples:

• An RSS feed icon is found on the main blog page next to the title.  This represents a feed for all blog posts.  As new blog entries are created, this RSS feed will update .
• There is also an RSS feed icon next to the title of every blog post.  This represents a feed containing all of the reader comments for that particular blog entry.  
• You can also subscribe to an RSS feed for each individual forum thread.  The RSS feed for each thread is a continual listing of all the reader comments and responses to the original forum post.
• There are also RSS feeds specifically for Chris' Blog and the Daily Digest.  The RSS for Chris' Blog can be found next to the title on the main page for Chris' blog entries, and the RSS for the Daily Digest can be found next to the title on the main page of Daily Digest entries.
