The registration ends on Sep 15, and the course is planned to start on Sep 17.
By the way, after this course I am also planning to organize another one about how to install and administrate debian-edu. I am going to demonstrate it by doing it in a virtual environment. If someone could help to extend it with some development details (the internals of debian-edu, the code, the scripts etc.) which might be useful for potential developers, that would be great. Or maybe the "development" part can be covered in a separate course. Anyway, we will discuss more about it later.
