I thought it might be not working, as my own email to him never got through. As for contacting him in any other way, it’s proved nigh on impossible. I have to therefore assume he’s retired to spend time with his cats 🙂
FYI, the most recent thing I found after an extensive google search is that he was part of a consulting committee about authors in schools in 2013-2014. So at least until recently, he was doing exactly as you remembered @thebibliosphere.
