RSS (Really Simple Syndication or Rich Site Summary) is a method of delivering news tailored suited specifically for your needs. Nikonians can be informed instantly of any updates to blogs, news articles or podcasts and organize them how you see fit.
The first step is to select a RSS feedreader. RSS feedreaders can be web or desktop based depending on your needs.
After installing (desktop) or registering (web), the next step is to subscribe to feeds. In the Nikonians page, simply look for the RSS logo and click.

After clicking on the RSS button there are various ways you can subscribe to the feed, by dragging the URL of the feed into the news reader or by copy and pasting the URL, while some readers it is possible to scan URL`s and find the feed automatically. Typically, sites that offer feeds use a similar orange logo for RSS, but some may just have a normal web link.
In some browsers, including Firefox, Opera and Safari, it is possible to automatically check for feeds for you when you visit a website (usually on the address bar).
Good luck and happy RSSing.
