I don't think it is a policy issue.
Hi @RPavlis, thanks for clarifying! This is a great question for firstname.lastname@example.org. Our Trust & Safety team has the necessary tools to answer all your questions about it.
Copyright is also under the purview of policy@Udemy, so yes they would be the people to answer your question.
I am not asking about copyright. I already know I have to give attribution. I am simply asking where people put this.
unless Udemy has specific rules about where you can or cannot put the attribution - it is not a policy issue. It is a design issue. Do you put them in a document? At the end of the video? Any other options?
