I'd like to add a jetpack subscription form below the content of every post. I know you can add the shortcode [jetpack_subscription_form] to add the form to "any" post or page. I'd like to know where I can put the shortcode to add the form to "every" post, not page, just below the content of the post. Ideally both in individual posts as well as the blog-style homepage.
http://www.girlwithblog.net is the site I'd like to add this on.
