Thank you! I have now been experimenting with it for a little bit.
In my environment, it looks like something is prohibiting me from allowing users to fill out the feedback more than once. This would prohibit students from being able to submit results for more than one class, wouldn't it? So the student sees the block in every course that it is mapped to, but once they'd fill it out once, they couldn't do it again in another course, it would seem.
