See http://www.learndash.com/why-moodle-is-becoming-irrelevant/ which actually made me notice our school demo.

School demo must not be stuck on basic Clean theme with some posts and blocks dumped on it, it's supposed to be an all-out flagship demo school. We've done so much work on themes etc recently and our demos don't show this off.

1) Switch to More theme with custom CSS where necessary to make it look slick.
2) Rethink the design of images/text/blocks on the home page to make it look actually active and attractive.
