There will be threads on it when they start sending them out. There are also threads from the past cycle, but there is no guarantee that it will be the same **** on the application. It probably will for most places though.
But don't worry about it. They usually just ask for quick statements (i.e., a couple paragraphs) in an essay prompt, and a few other questions that they already know the answers to, based on your primary application.
There are very few that actually ask much of you. I think Western had a long one, and maybe KCUMB. I can't remember who else.
