Copyright

I thought that sections like this could be skipped. But people seems to think that everything on the Internet is free. For simplicity, I will say that nothing can be copied from this website without my permission. I will grant permissions to some organisations (in general, I will NOT grant permissions to other public websites), but you must contact me in advance. I understand that english is not the main language for everyone, so that is why I want to be contacted, so that the copyright information is not misunderstood. Thanks!
