The "Post List"

Go to your list admin page:
http://www.west-point.org/<category>/<listname>/admin

<category> = society, family, parent, wp, etc.
<listname> = usma1964, wppc-alabama, wps-houston, etc.

Enter your username and password.
Click on "Simple Listserv database interface; Edit member db"
You will be redirected to the new admin interface.
Enter your username and password again.

Either your membership list will be open, or, if it is too large to view, you will have to click to open it in another browser.
