I am presently going through the list called Chinese Illustrated Dictionary and I noticed that a word that I had previously learnt there was recently revised. The revision in question was from 鲶鱼 to 鲇鱼 (an essential word to know, I'm sure you'll agree :P).
Apart from the fact that (as far as I can tell) this is a meaningless revision (Nciku says both entries are OK) I also noticed that the new entry had been left unstudied (I don't know whether the old one is still in my database or not?!).
But the point is that if lists that we have already finished learning are modified in some way, the new words don't seem to be automatically re-added which is kinda annoying. I hope that some of the other lists that I have 'finished' don't have this problem!? Is there any way to fix/improve this?
