If you have an account on icarus(students) or tigger (staff and faculty), you may create your own personal web pages. If you are a faculty or instructor, you may however, create class related web pages that are in a shared space where the disk space used by the class related web page is not counted as part of your own personal disk quota. Same applies for departmental web pages.
For more information on setting up web pages, please refer to http://www.uic.edu/depts/adn/www_publish/
