I think there is a bug with adding words.
On 6/8/12, I added 输在起跑线上 from my Chinese Pod list. *Just now* I got the writing portion - there is a note to the bottom left that says "new writing".
It has never taken that slow before to add a word. Since 6/8/12 I've studied the definition and the tones of 输在起跑线上. Why did it take 2 1/2 weeks to add the writing prompt?
