Some info about OpenID

Go over to http://myopenid.com/ and get yourself an account then add the following to your homepage:

<link rel="openid.server" href="https://www.myopenid.com/server"/>
<link rel="openid.delegate" href="http://yournewid.myopenid.com/"/>
<meta http-equiv="X-XRDS-Location" content="http://yournewid.myopenid.com/xrds" />

Where you replace the 'yournewid' parts with your new myopenid. Then you can login to sites that accept opeid using your regular website as your url. See the page at openid Enabled about using your own url
