The problem with places that have networks set up such as colleges, universities, work-places and so forth, is they often have network firewalls that block a lot of the ports needed for IRC access. This is in fact often intentional due to the dangers that IRC could bring to a network (for example, obtaining a virus from DCC).
You'll need to talk the teacher/professor/etc in charge of that area of the college (computer/internet setup) and see if they can help you. Not much we can do this side.
Or is it a GameSurge specific issue? Can you connect to other IRC networks?
