It gets really frustrating when a comment is made on a blog post and I go to reply to the kind commenter and it comes up email@example.com. By default, your email address is not shown in your profile and with Blogger profiles now being attached to Google+ profiles you have to tell it do un-attach. In the past, you might have been a reply blogger but if you have connected your blog to Google+ it has changed. Do you know how to find out if you are a "no reply blogger"?
Here is the best, and I mean the best, instructions for setting your no-reply back to reply.
I highly recommend you at least check to see if you are a no-reply blogger. Because if you are, there is no way for me to reply to your kind comments.
