title: Creating an OpenID login widget
body: <p>I need an OpenID login widget like the one on Stackoverflow or <a href="https://www.idselector.com/user/login" rel="noreferrer">Id Selector</a> (which has been discontinued in favor of RPXnow which is a commercial service). </p>
  
  <p>What is the best way to make these? Is there a framework or example implementation anywhere?</p>
