What you put up in your Agnes Waypoints space rests entirely with you. You can choose not to pick a subdomain that reveals your name or you can use a pseudonym on your actual site. It is your responsibility to set portions of your site as private as the default setting is public.
Always remember that you must abide by the following college policies: Acceptable Use, Copyright, Digital Millenium Copyright; and the Agnes Waypoints Terms of Service. You can find these items under Agnes Scott Information
