<p>If you have a private network where all sites are open to anyone with an account, but still want the ability to invite someone from outside and limit their access to a single site, then Network Restricted Members is for you.</p>
<p>This plugin was developed for our private <a href="http://p2theme.com" rel="nofollow ugc">P2</a> network, which is open to all company employees. However, we still wanted to be able to bring contractors and clients over without giving them access to everything on the network.</p>
<h4>Usage</h4>
<p>Network Restricted Members provides a user setting that allows multisite network administrators to restrict a user to the sites he or she is a member of.</p>
<ol>
<li>As a super admin, navigate to the Users dashboard</li>
<li>Click ‘Edit’ on the user you wish to restrict</li>
<li>Check the option ‘Restrict User Access’</li>
<li>Save your changes</li>
</ol>
<p>From this point on, administrators will need to add this user to their sites before he or she is able to see them.</p>
<p>If you wish to lift the restrictions on a user, repeat the steps above but <em>uncheck</em> the option box instead.</p>
<h4>Other plugins</h4>
<p>Network Restricted Members works best when combined with a network privacy plugin, such as one of the following:</p>

<p>The plugin uses standard WordPress hooks:</p>
<ul>
<li><code>authenticate</code> – To check if a user is blocked during login</li>
