I have been doing this for a while, so disappearing was not even in my thoughts. :)
But I'll need to think about that and how to make it clear for everyone that visits the school.
Thanks!
Partially because the video player doesn't work very well on tablets, and partially because after you changed the game engine course, I still wanted to refer to the original version
I've read through your FAQ, but one more thing to consider is to offer a bundle discount, like for buy all or similar.
To be frank, this is not very re-assuring. Every platform that has ever gone offline has at one point told their customers something similar.
It's also possible you may go offline for reasons outside of your control.
I see. I've just discussed about this with other people at the school. I guess if something like that ever happens, the course content will probably be made available in full to all students.
One thing is that I am personally always updating the course and adding new examples and lectures to it. If students simply download the content once there will be different versions of it. This was one of the reasons I've decided to record lectures instead of simply writing a book, for example.
