Great news Phillipe! Thanks for the feedback. It's good to know the installation went wihtout a hitch 
I think what would be most persuasive is a demonstration of some "adaptive" learning materials you could make using a "smart" chain of Hot Potatoes quizzes.
For example, you could make a chain of 3 JMatches followed by a JCloze. The JMatches prepare the students for the vocab to be used in the JCloze. Each JMatch has 12 items of which 8 are displayed, but each JMatch presents the vocab in a different media, e.g. text-text, pictures + audio words, word text + audio sentences.
Add pre-conditions so that each quiz can only be attempted once the previous quiz has been finished. Add post-conditions to the JMatch quizzes so that if they get over 80% then can go on to the next quiz, otherwise they have to retake the same quiz.
Something like that would work. You can probably think of something far more interesting and methodologically sound, perhaps using HotPots you have already created.
Sorry there aren't any tutorials or written instructions on what to do yet, but if you are familiar with how the HotPot module does things, you already know how to create quizzes on your PC, upload them to Moodle and add them in one go as a "chain". The difference is that now a "chain" remains a single learning object. Moodle refers to it as a QuizPort activity.
all the best
