This client, and I think rightly so, has had negative feedback about the email icon being used to depict the "Subscribe to blog" link. I agree, it's not intuitive. A better (and much more common - at least in past years) would be the RSS icon - fa-rss. Is this editable from the Settings, or do I need to either edit a file (if yes, which one please?) or create an override?
I couldn't find an icon that actually says "Subscribe" but that would be even better. Let's not make readers play "Guess my use"!
A later thought: Why not, on the "Frontpage", add the same thing you have on a post page - the icon and link that says "Subscribe to this blog post" but change it to "Subscribe to this blog"? Much clearer for users.
An even later thought/request. The client doesn't want visitors to be able to subscribe to a specific post but wants every "Subscribe" to subscribe a visitor to the blog. So all existing subscribe links should stay in place, but they should all just subscribe the visitor to the NorCalPulse blog in total.
