Has anyone heard anything at all about PC?

Unfortunately no.
He was travelling abroad (so someone said) and it's years that we do not hear news.
Me too I asked the same question months ago.

Has anyone tried emailing him? I just sent him an email. Hopefully he answers.

I hope he does too.

I hope he does too, Rod. I seem to recall him saying he was going to Africa the last time I remember him posting (but memory cells fade). Hate to think that anything bad has happened, but he's not posted anywhere here, Flickr, or Deviant since then.
