I'm a great fan of SRS and I think the review application here is quite good. But I wonder if there's a better way to implement the definition questions (you see some characters, then type the English definition).

E.g. if I see 骗子　and type "cheater", and then it says "wrong: it should be swindler", that doesn't work for me. Then you spend part of your learning energy memorizing which English synonym to use for a specific question, rather than learning vocab. But picking an English definition from 4 options is usually much too easy.

Maybe something like the "Chinese memory game" at www.yellowbridge.com might work?
