The "copyleft" link at the bottom of the page goes to his license choice.  It's basically non-commercial and a requirement to attach a copyleft logo to the page.  Can we create a custom license in the drop-down that has those elements?

Side note: we contacted the author and the text is his.  The images are problematic, but we are not using those without confirming the original source.
