I love the flashcard program built into this site. I've seen other programs that use the boxes, but not on a calendar system like this one "AKA on the ones I've seen you can get to the highest box in one session if you want".

Does anyone know of a good flashcard program that uses the boxes, and a calendar system that I could use for managing my vocabulary?

thanks everybody! ありがとございます！

I can't download it right now, but from looking at the site it looks really good! thanks!
