Perhaps running as root is a bad analogy but if someone sends me a link saying I found a bug on your site at
http://mysite.com/acs-admin/users/nuke-user?user_id=myuserid
it would be nice if I had to at least login before it did it. Anyway the more barriers that keep dumb stuff from happing the better. I don't want to go back to lynx to surf the web.
