Information about member PS?

Does anyone know the status of PS? PS hasn't posted a blog entry since 2013, and isn't responding to message requests. I'd like to contact PS since PS is the most recent contact point that I've been able to track down for The Professor, whose permission PS received to repost some of his stories on this site back in 2010; using the Message To The Author link from The Professor's stories on this site generates a message to PS.

Thanks!

John Mead
