I used my wife's computer to visit this website. I tried to log in, but OpenID would only log me in as my wife (obviously she has stored her login credentials in one or more cookies on her machine). Surely there is a way to get OpenID to permit an alternative login - only I don't know what it is. REALLY IRRITATING!
How does one login using OpenID on a machine that other people use and have left "id cookies" on?
