Not a bad idea. I want to wait and see if they will tell me what the

about it.

They probably CAN'T do that, but if you find somebody cooperative, they
can possibly give your name/info to the other students. They may have
to do it through the course instructor, who undoubtedly has an interest
in actually teaching the course so he gets PAID. I think it is pretty
kosher for an instructor to solicit enough people to actually teach the
course.
