If anyone has been wondering as to how they can join a network and get questions on academics, financial aid, GPA, good professors, and on campus activities, at UNLV there is a social network called freezecrowd.com
Basically freezecrowd is an interactive yearbook with all of the above, but you will have to register with your EDU email and look for the confirmation email, prior to logging in.
Its been really helpful to me as a Math major and feel free to message if I can be a resource. Thanks!
