User can subscribe to RSS feed at following different places in alfresco share - Wiki,Blog,Document Library,Links,Discussions,forum,My Activities dashlet on your personal dashboard and Site Activities dashlet on the site dashboard.

Once you click the RSS feed button at any of the above places, it initiates the subscription process and next thing you see completely depends upon the browser you are using. Then choose to subscribe to feed and select where to store the feed and subscribe it.
