I'm just dropping a note to let you know about a mistake in Spanish Level 2 Session 20 - "Write the words you read". Expensive/Caro and Cheap/Barato are mismatched. There was another similar mistake in an earlier lesson, but I don't remember which. It was a 'type the translation' exercise, and I'm pretty sure it was a tu/usted mix-up. I'm not entirely sure though. I started over from the beginning with Fluenz, so the mix-up would be somewhere around the end of Level 1 or beginning of Level 2.
