I accidently deleted the RSS feeds when I first installed movable type so I thought it would be appropriate to bring it back. There are two seperate feeds since there are two main sections of this site. The first feed is for the main site or the page you're reading right now, basically everything that isn't in the class room. As you may already have guessed, the second feed is for the photoblog/classroom area so you can stay up to date on newly released photo tutorials (and they don't come often unfortunately).
You can find the two feeds on the left side of the main page. Should not be hard to find!
