The QtAcademy is not working at all:

• No courses available
• One learning Path, but this one can not be started when clicking on a Content Tab and a click on the content doesn't do anything
• The forum is not working as well because the "topic" field is mandatory and it doesn't show any entries for "learning path" or other sections
• No way to report a bug or any feedback for the QtAcademy or having any mail address or alike

You shouldn't announce a new product without any function or benefit.
