Hi Sarah

"...a lot of folks are more interested in being WordPress power users than they are at being developers.”

That makes sense to me.

I use premade Genesis themes to provide small business websites and I customise with plugins and custom CSS.
I've never really been interested in getting into PHP.

Like most people I learnt what I know about WordPress via internet posts and videos and help from the Genesis community but I can understand that there is a big demand for more formal WordPress courses.
