Yes I totally agree with DJay. I've tried going to the admins of my high school about problems, only to have them laugh in my face. But I laughed whenever they got in trouble for all the security flaws ;D Though letting them know at least lets you know that you did the right thing, it is up to them to take measures.

I would think though that if you might know any staff members of your college, maybe you should let them know so they can actually talk to the admins or place "help desk tickets" like we have here at Penn State. That way the problem can be logged and dealt with, and you don't really have to have your name mentioned, so you can't be acused of doing any "hacking".
