Course Sniper

[KentCurtis]

Hey all, I recently used the service offered by coursesniper.com and it really did work.  I was wondering if anyone had any insight on how they made this site work?  It basically checks classes and notifies you via text, call, and email when a spot opens up for a class you want to take. I know at least for my college you have to have a user/pass and be enrolled to be able to view available classes, and even have to be approved for registration to know whether or not there are open spots - so how does this php app work??? It sure is brilliant.. thanks all
