It looks like he has abandoned the website and moved onto Facebook - regretfully a common scenario.

I'm not a member of Facebook so I can't see what's there, but I can see a post* from 22 January this year which seems to be by Robin. So if you know someone who's on FB you could ask there.

* The post has a little globe next to it which, when hovered over, says 'public' but if I scroll down to read it the page is blocked. Maybe 'public' doesn't mean, er, public? (Or as Ewan MacColl and Peggy Seeger sang, 'the public's the public any more'.)
