This is a typical user portal from sloanspace.mit.edu. In this case, the portal is used primarily in combination with the ACS Education Module. This portal provides a single point from which a student at MIT's Sloan School of Management can manage all of the information that is relevant to him, personally.
A portal may span multiple pages. This portal happens to have five: MySloanSpace, Calendar, New Stuff, My Files, and Class Documents. Currently, we're looking at the MySloanSpace page.
