I recently did a google search for some perl documentation and I came across the perl cd on a university web server. It appears to be a student's account. I sent webmaster@the_school.edu an email regarding this matter and how I though it was a copyright infringement. (All very politely) I plan on checking on it in the next day or two to see if it automagically disappears.
Was that the correct thing to do?
If not, what are you supposed to do when you come across intellectual property that you belive the copyright has been abused?

Update: I just received an email from the guy that had that account and the cd is no longer accessible.
