Often times I would come to a work station, attempt to write an aLOG entry, and find that the web browser has someone else's ligo.org credentials in place (either from recent use or a stored kinit), and I have to close and restart the browser before continuing, or run kdestroy. One should have the ability to log out, or at least have a "Not You?" link that takes you to the home screen, clears the store credentials, and asks for new ones.
