I just changed the address of our site from
www.atrl.net to
atrl.net, which removes the useless "www" prefix. This is to follow the trend of many modern web sites; no one needs to use the "www" anymore.
It signed me out when I did this, so it probably signed out everybody else too. You will just need to sign in again. Let me know if you're having any problems remaining signed in. Be sure to check "Remember Me" when you sign in.
