The XML icon for the site's RSS feed appears on the left-hand side of the screen, and the feed works when I add it manually as a Live Bookmark in Mozilla Firefox. So the site is certainly capable of RSS feeds.
However, I think the convention is that sites with RSS should also advertise this fact by adding metadata to the page header, which MaplePrimes doesn't yet do. An example of this metadata is:
<link rel="alternate" type="application/rss+xml" title="RSS 2.0" href="http://examplesite.com/feed/" />
<link rel="alternate" type="text/xml" title="RSS .92" href="http://examplesite.com/feed/rss/" />
When I use Firefox to open a webpage with this metadata present, an icon appears in the bottom right of the page which allows one to add the site as a live bookmark.
This is a fair bit easier to set up for people who don't have prior experience with RSS than manually extracting the URL to the RSS feed and adding this as a live bookmark.
