Is anyone here a member of the ACM?

Has anyone here ever done a peer review of a paper using the ACM format?

I am doing this for a class, but my teacher is not responding to my emails about the format to use for the review. I haven't had any luck searching the Internet for the specific format, either. Just curious how I am supposed to do these two reviews I have to do (and both papers are fucking horrible! One of them has 3 cases of plagiarism, so he's failing the class already).
