I am a hobbyist mathematician in China. I study maths by myself and make some course videos to teach commutative algebra, functional analysis and other topics on the internet, like the Khan Academy and MIT open courses.
Now I need a .edu email to get into some sites such as ResearchGate and arxiv. Is there any organisation that will help me like this: I show them some material, such as videos and papers, and if they think I am no weaker than some college teachers at least, they would give me a .edu email?
