Your web address should be:

www.earlham.edu/~username

where the word "username" is replaced with your username/user ID, and the character before your name is a tilde, made by simultaneously pressing the shift key and the key in the top-left corner of your keyboard (not "Esc").

The entirety of your home page address is:

www.earlham.edu/~username/index.html

but Netscape automatically knows that the file called "index.html" is your first page so it goes there without being told. To go directly to any of your other web pages you would have to type in the entire file name including the ".html" ending.
