Go to a blog you like reading, and click on 'More options'. Here you'll find the possibility to subscribe to a blog! This function is also present at the bottom of a blog page. Perfect for newsletters and frequent users.
Thanks to this function you can receive each new article on the blog you have subscribed to (max 3 per day no worries 8) ). People without a Skyrock account can also subscribe with their e-mail address.
Not bad huh?
