Question on simplified and traditional Chinese characters:
Not sure if you're aware that some text passages I posted in my page have full form/traditional Chinese characters (Taiwan, Hong Kong) and some have simplified characters (PRC). Only some characters have been simplified (a few thousands), but they include many common ones.
I think most students remember and type simplified characters but not traditional (which we generally try to avoid)
If one adds the simplified form to the card in the "Alternative" box for a traditional character, would that upset your database?
Since your dictionary works so well with both forms, I would suggest having 2 boxes for the character in the flash card: 1 for simplified and 1 for traditional.
