You will need to speak to your network administrator at the college to get help in setting up IRC. If they will not help you, then we respect their wishes (preventing IRC access is perfectly understandable given the dangers that can be encountered). Most people here, including myself, probably *can't* help you bypassing a firewall anyway, as firewalls can all be different and we don't know how your college one is set up. As I said, you'll need to speak to the appropriate staff.
