Lately it seems like adding words to the database has become less easy than it used to be.
A lot of times I'll put in the pinyin and the definition, and then click "create word", but then it the word will still show up as not added to database, and when I try to add the pinyin/definition again, it says "already in the database" or "incorrect pinyin".
What I've been doing is adding the word again but with another few characters so that I can try to get in it my list.
