first the graphic version (click to embiggen)
and the long wordy one,
there is a easier way. on the top of the page there is a dark gray bar – look for “Subscribe” and click on “Subscribe to blog”. this is available on any WP blog, I think.
on the same bar there is “My Subscriptions” where you can click to either read your subscriptions, and also “Manage my Subscriptions” – the default is to send an email when there is a post, but you can change it to no emails, or emails from some of your subscriptions only.
