WSO account
From Willipedia
A WSO account, as distinct from your Unix ID, lets you put up a web page that begins with http://wso.williams.edu, and use the features of our web server (CGI, PHP, MySQL, PostgreSQL). It also allows you to use the WSO Secure iChat Service and gets you a WSO email forwarding account. You need a WSO account if you're going to maintain a website for a student organization or cluster.
