Email Subscription for a Blog

I just found out how to create an email subscription service for your blog! These instructions are courtesy of ThemeLib:

First, use Feed Burner to share your blog:

Then, create an email subscription widget and add it to the design of your blog:

Lastly, please look to the right and sign up for emails on THIS blog, if you're interested. :)
