If you're reading this you are probably either an MUM student in a class that uses this machine -- or someone related to a student interested in seeing their work.
If you know the username of the person whose home page you want to see, you can go there by putting a ~ in front of their username on the URL bar. For example http://mumstudents.org/~kadely leads to Professor Daley's page.
Course materials are sometimes also hosted on this machine. For example: http://mumstudents.org/cs472 takes you to the course material for CS 472.
