And how many, equally many, adult researchers (myself included) were fortunate enough to find this board when first seeking answers to questions about Lincoln, and the assassination, and then stayed to marvel at the breadth and depth of knowledge exhibited, and freely shared, by Roger and members of the board. As far as I know, there is nothing else like it, and yes, I agree, David, countless people of all ages owe a tremendous debt of gratitude to Roger for his dedicated, tireless work!
