Mads recently posted an article that outlined how to use OpenID on your website.  This code is really cool as it helps further the OpenID platform.  What is OpenID?  Well if you are unfamiliar with OpenID then I would recommend that you take four minutes and watch this excellent video that explains it perfectly!

Now that you have an understanding of OpenID and want your very own OpenID account you can look at this exhausting list of OpenID providers to see if any fit your requirements.  I chose SignOn because it allows me to login using Information Cards so that I never have to enter a password.
