You can find out when new themes are released by subscribing to the Question Writer Newsletter, or you can read the regular updates on the blog. 
To add or change the theme, click the 'Switch Themes' button. A list of themes will appear and you can select a different theme. A dialogue box will appear telling you that the theme has been changed.
You can then Preview the quiz to see how it looks with the new theme.
