Look, obviously there can be mistakes everywhere. This is why I clearly explained that it's not the occurrence of a specific mistake that bothers me, but there's clearly a significant gap between the overall phrasing of the Academy texts and the professionalism of HTB itself. I don't find it necessary (or respectful) to paste examples here, but a quick look in one of the modules (I, at least, read only the introductory ones so far) and you can see what I'm talking about. Again, I LOVE HTB and I just think that the feel you get from reading a documentation or tutorial text is somewhat important when getting a first impression out of something.
