私は日本語で書けますよ

Look at what I finally figured out how to do: 私は日本語で書けますよ。That's right, I got my computer to finally write in Japanese.  But Dude, you say, that's great for you, but I can't read Japanese.  Well, I have the answer: Babelfish except, it's not so hot. It translates the above statement: You can write me in Japanese, when, in fact it says, I can write in Japanese! I don't know why it's confused. Also this, 私は日本語で書くから私はあなたより元気だ。This translates correctly, but I know for a fact you should say: 私は日本語で書くから私のほがあなたより元気だ。Oh the humanity.
