RateMyProfessors replacement?
RobGR: Without anonymity, will people post ?  If they have to use a school email to post, will they be anonymous ?  If you send an "account confirmation" email to the student's address, won't some idiot at the institution read it and try to use it to deduce who is giving certain reviews ?Maybe one way to get an edge and get started, is to also allow rating of a lot of other stuff besides professors.  Rate administrations, lab conditions, dorms, frats, etc.  You could even have a way for Professors to rate their students, and for students to rate students.Maybe to keep it at least slightly positive, make it so there is some kind of reward for posting positive reviews ?
