I was reading an article on Read/WriteWeb about OpenID which aroused my curiosity. After an initial research about OpenID, I wanted to use my own domain name as the OpenID URL and was fortunate to find this by Simmon Willson. You need to just follow the instructions and add the Code in the header.php of your Theme. MyOpenID is a OpenID Server, which provides you the the Service. They even have an affiliate programme which will help you have people logon to your website using OpenID. I intend to submit my affiliate request for verification with them.
OpenID is gaining tremendous momentum as AOL , Microsoft and Digg announced their support recently.
