NikkoSets - Free Learning Platform & Quizlet Alternative

I was in school, learning on Quizlet, until I got hit with a paywall disrupting my learning. Until I decided to make my own learning site for others as well to have a great learning experience without having to put a single PENNY into unlocking extra features, now and forever NikkoSets will be free. It will contain as much features as I can possibly think enchanting learning experience, and ideas you guys can suggest me!
