Catherine,
You definitely understand the concepts behind the regulations. Unfortunately not everyone has the same level of common sense about what is appropriate for admissions to say. It is also unfortunate that there are still schools, unlike yours, who simply do not keep their admissions staff informed about these important regulations. As you are truly the face of your school to the public they simply must keep you informed and up to date.
I know it must feel good to know your school is doing the right thing!
