Congratulations goes out to Luke McDonald as one of the themes produced by Press75.com has been selected to be part of the WordPress.com commercial theme store. The theme is priced at $50.00 and is called Debut. It’s mobile ready right out of the box along with having post format support. Speaking of post formats, Debut is especially interesting because when users select the Audio post format, it expands into a multi-track playlist. You can see the theme in action via the WordPress.com theme showcase.
