I love this plugin! We are using this to generate a weekly newsletter for a local school, complete with excerpts of the latest post of our choosing and thumbnail images. It's a wonderful way to keep parents up-to-date on the latest news.
We purchased the pro version of the plugin, and had a slight issue upon install, but tech support responded within 24 hours.
We don't really need the PDF feature, but the newsletter feature is great.
I highly recommend it.
