Update: There was a bug that limited lists to 3 entries, this has been fixed. Mina-san, gomen nasai!
I am happy to announce a major site upgrade. You now have the ability to create an account, from here many new site features will be linked. For your convenience, you can login via a variety of external login services (Google, Facebook, Twitter) .
The first of these features is the ability to create your own study lists (currently Vocabulary and Kanji). Coming soon will be an update that allow you to drill your study lists or the public JLPT lists as another tool to help you learn more effectively.
Please leave some feedback if you have any issues or suggestions.
