Thank you for the update Robert, and I'm very sorry for the loss to you and your family. Paul was an amazing member here, with many many valuable posts. I hope you are okay with reading back through some of them to see how integral he was here at PF. You can see those posts by clicking on USER at the top right of the page, clicking on his username and then clicking on Postings. That will show you his posts in reverse time order. You can also do a forum Search (at the upper right of each page) and fill in his username.
He will be missed very much here, as I am sure he is missed by your family. My impression is that he has led a long and wonderful life, which is a good thing. RIP.
