I have been using WordPlay now for about 6 months and I have to say it's the best long form writer I've ever used. My fave features are:

- different ways of writing long form content (via headings/subheadings) or from a list of titles
- easy upload to WordPress (although if you the dev could make it more seamless it would be even greater!)
- impressive quality of the content produced

Keep up the good work!
