Holy cow, it seems that rumors of Mr. Arneson's death were greatly exaggerated, so I have retitled this post, but it remains a thank you nonetheless. It's good to have a chance to thank someone who has contributed positively (if indirectly) to your life before it is too late! The rest of the message remains the same:
Thank you, Dave, for contributing to the foundation of my very favorite hobby for the last 17 years or so. Gaming is part of my everyday life, and it might not have turned out that way if not for your contributions.
