I'm conducting an UE4 workshop to the students who have signed up recently. I need to apply for copyright and to make an Intellectual Property Agreement with them to protect my teaching contents since I'll be giving all the lecture notes, 3Ds max and UE4 scene files to them. You may refer what I have written in the [url removed, login to view] to prolong it to a proper agreements (example) that attached for your reference. About the copyright, I'll need your help to provide me some great & trustworthy copyright registration websites to register my copyright online! So you will have 3 days to complete it as I need all these to be done ASAP by next Monday!
