Gordon,
Thanks for your response. I had hoped that Quandary, like Hot Potato, was well-integrated into Moodle. I like the integrated Quandary approach to building decision tree exercises. Of course, I know I can get roughly the same thing using other Moodle Question formats to build a succession of question chains, and that is probably what I will end up doing. But first, I wanted to see if Quandary had any possibilities. Maybe when I have time, I will return to it to see what can be done. But for now, deadlines are looming.
Thanks again,
Rod
