This is amazing work. I have a website that does some work with Super Mario Maker called https://makersofmario.com we already have our own ratings, tagging and comment system working with the exisitng WiiU levels. When SMM3DS was announced without online play we planned to try and add support with our site as well. I know you mentioned online support almost completed but we would love to help in anyway we can and maybe combine forces if possible. Let me know and we can try and work together!
