You will probably find that your school has a firewall that blocks access to some sites, including some webmail sites like MSN Messenger. This is to prevent young people from wasting their time on e-mail when they should really be using the school's PCs for more educational purposes. If your school is anything like the one where I work, it will also have e very vigilant IT Manager, who can "see" exactly what web page is being viewed by any pupil at any given time. If I were you, I would be just a bit careful!
