Two problems with this:

1) She can only bring a discrimination case if she doesn't get hired and can show it's because she was female. If they hire a better male applicant, there is no case.

2) If she brings action against them which fails, I am then wide open to libel and / or slander.

Oh, I completely realize there are problems. Just pointing out what else could be done. Also, she doesn't have to bring a case against them, nor do you need to present yourself and leave yourself open. Not sure if just letting her know anonymously would do anything for her. Personally, I'd want to avoid working in such a place.
