Can't get logged out so DD can register

[JNorris]

I am trying to log out of my user name, so DD can get on the DisBoards and register her username. I click Log Out in the upper right corner, and the next screen shows I'm logged out, but anywhere else I go from here, logs me back on again. I don't want to clear all the cookies on my computer, I have some sites that I don't want to lose my automatic log-ins.
