Bookmarks enable you to list community content (boards, articles, ideas, topics, or individual posts) on a special page so you can easily find it again.
UPDATE 17-05-2014: The bookmark/favorite function is no longer available as we decided to remove this.
What is RSS and how do I use it?
RSS stands for "Really Simple Syndication." It is a way for you to get the latest content from this community, along with many other sites that you visit, all in one place. With an RSS feed reader, you subscribe to web sites, and those sites feed you headlines so you can stay up to date.
To use RSS, you need a feed reader, such as Google Reader, MyYahoo, or the Live Bookmarks feature of Firefox. There are many free options. After you have your feed reader set up, you can find RSS feeds in the community by going to a board section and selecting RSS Feeds in the bottom of the board. There you will see a preview of the feed. Most RSS readers give you a button to click at this point. After you click it, the RSS feed appears in your reader as well as new content from that section of the community whenever it becomes available.
