Don't remember of the top of my head.
I've since learned I can PM him if I click on his name in any of his posts except his first post in the thread (he was original poster). When I click on his name in the original post, I'm directed to his member home page. If I click on his name in any of his subsequent posts in the thread, I get the drop down menu that allows me to PM him.
Thanks for the help and persistence!
