John Clemens

Does anyone out there know who/where John Clemens is? I have run across his name a few times within the Inform 7 documentation but his name does not show up in the extensions lists. Jim Aikin and Aaron Reed both mention him in relation to an extension but nothing shows up in any search (at least not searches I have done.)

He’s got an IF web page at

I tried contacting him in relation to my update of his “Conditional Backdrops” extension, but did not receive a response.
