Smashwords.com does not allow one to publish works serially. It's a policy.
So, you cannot download the Liz chapters individually off of Smashwords.com. Sorry. At the moment, you can do so on Amazon.com.
I suppose I should check to see if Amazon has a similar policy. That would be the responsible thing to do. I'll let you know when I figure that part out.
I plan to make this blog available for subscription on Kindle, too. That might be a good option for some of you.
