I sent yesterday a question through the list. I think I wasn't too clear about it, so I'll try to explain myself some more.
That person is offering me money for me to read and explain to him the different steps of his legally-owned diagrams, so he can make the folds as we go along. As I mentioned, the diagrams correspond to authored models as opposed to traditional ones. I'm lost regarding this particular situation because it's somewhat related to, but simultaneously different from, teaching an authored model to someone else for hire without the creator's authorization. That is NOT OK: See here: https://origamiusa.org/faq/copyright-0#t67n172 The person who contacted me simply wishes to fold the models from his diagrams and doesn't know how to read them. He's an older man, and also a very able folder, who never learned how to read origami diagrams and isn't at all interested in learning now. That's why he offered me money to help him. Can you please share with me your thoughts and advice? Once again: I really appreciate it if you also forward your answer to me, or sent it only to me, if you prefer to be private. I'd start with him latter today so I also appreciate prompt answers. Thank you once more : )
