WOW! I'm excited about all the features!

I’m a teacher and I was very happy with my first experiences with Watu. So I bought WatuPRO for professional usage: I love WatuPRO not only for his abundant functionality but also for two educational reasons:

1. You can design quizzes with all the power WordPress offer. (Watu uses the WYSIWYG-editor, text for qeustions, answers, feedback etc. may be as long as you want; you can include links, pictures, videos etc.)
2. The Plugin is educationally sound and features modern educational theory. Some examples: You can elaborate special feedback for each given answer. You can provide quizzes for unregistered users in practice mode. You can set up dependencies and chained logic in order to present the most adequate quiz for the learner automatically and much more.

The only thing I’m missing: A systematic written manual where all the huge functionality with their shortcodes, free add-ons, free bridges etc., can be looked up. (For the beginner some screencast to start with Watu(PRO) would be also very helpful.)
