In Help Center, you have the ability to "follow" Sections and Articles. The "follow" feature works like an RSS feed. If you follow a section, you'll get an email every time an article is added. If you follow an article (such as a specific Known Issue in our Knowledge Base), you will get an email every time the body of the article is updated.
HOW TO FOLLOW:
Click on the Follow button in the upper right hand corner of the article or section:
To follow a section --> Select "New Articles"
To follow changes to an article --> Select "New Articles & Comments"
HOW TO KEEP TRACK OF FOLLOWED ARTICLES & SECTIONS:

HOW TO "UNFOLLOW":
Within My Activities/Following you can simply click on the "unfollow" button for any section or article:
