<p>On October 14, 2015, LinkedIn converted all groups to private,<br />
    which has made the groups display functionality of this plug-in<br />
    impossible.  However, the Sign in with Linked functionality still<br />
    works perfectly fine.  The associated sign-in and registration hooks<br />
    offer great flexibility for utilizing user data in custom coding.</p>

<pre><code>var $j=jQuery.noConflict();
// Use jQuery via $j(...)

$j(document).ready(rdp_sign_in_onLoad);

function rdp_sign_in_onLoad(){

        event.preventDefault();  
        var redirectURL = $j(this).attr('href');
        jQuery.cookie('rdp_lig_login_redirect', redirectURL, { path: '/' })
