Hi, Barbara. We are all very sorry for your loss. Jim touched a lot of us over the years. I have been lucky enough to work with him at Tech sessions over the last 6-7 years, and to have known him for the past 15+ years.
An announcement of his passing was posted here Friday night. Here is a link to that thread, where many members of this forum have been expressing their condolences and rememebring Jim.
