We’ve created a dark template, is ready to use with widgets integrated into 2 columns, has ads space and uses side tabs. It’s great and easy to use. The background is black with green backlight of options which makes it look spooky in a way. Please note that you have to copy the plugins inside into the wordpress plugin folder and after that activate them in order to make the template work correctly. Enjoy. It’s 100% free!
