Very sorry to hear this sad news. Jan was a great guy and one of the nicest people here on the forum.
I never met him in person, but a few years back, he and I had a nice conversation here in the Coffee House about both of us being at the massive Concert 10 Rock Festival (along with about 230,000 other people), and we enjoyed reminiscing about our experiences at that wild, crazy event.
Rest in Peace, Jan, and sincere condolences to his family and friends.
Bob
