As I’m moving to a VPS hosting, I’ve decided to remove the temporary homepage for WordPress plugin ‘Simple Portfolio’ which was located at http://projects.inlet.nl/simple-portfolio-wordpress3. It was mainly focussed on how to use the API. In meantime the plugin has been evolved to a more mature version and the old plugin homepage doesn’t fit the requirements anymore. In fact you can expect more updates of the plugin soon and I’ll create a more decent theme (maybe based on the default twenty-eleven) which can be used as a plugin reference/wiki as soon as all new feature requests are implemented.
But for now you’ll need to stick with the existing sample theme.
