Can one create their own themes and if so, are there guidelines? It would be fun to have more themes
I figured out how to change the background image, the body fonts and the header background. Will look deeper later but am happy with the work so far.
The best approach here is to take an existing theme, change the name of the folder, and update the details in manifest.php. The folder and theme name must match. Then hack away at the images and main.css. If you come up with something you want to share, let us know and we can look at hosting it on our Extend page.
