I'm sorry but the above responses are incorrect and following that advice could result in triggering the Long Form CDR.

With CDR's you ABSOLUTELY do not want to being adding ANYTHING into the notes section, write on the back of forms, or attach anything!!!

I do not remember the space being so small that you couldn't even write Obsessive?

PLEASE read this before starting on the form! http://nymakesworkpay.org/docs/Guide_CDR.pdf
