My name is Henryk and I am technology leader at Black Belt Factory (http://blackbeltfactory.com). As some of you probably know we love Vaadin here at BBF :) We've rewritten our site using Vaadin, created comprehensive Vaadin Fundamentals course (and exam) and now we want to expand our Vaadin courses and exams even further.
We crated draft  of the table of contents for the next Vaadin-related exams we want to create on Black Belt Factory. We would be grateful for any feedback and comments regarding the quality of the proposal of the exams structure.
