<li>From the Projects Page in WP Admin , there will be an option to <code>Request Client Recommendation</code> & once you click on it , an email with the password along with the link 
to submit the recommendation will be sent.</li>
<li>The client upon receiving the email, he will be redirected to the Project page where he will be prompted to enter the password that is mailed to him.</li>
<li>Upon entering the correct password , he will be prompted with a form to submit his recommendations.</li>
<li>Once the recommendation is submitted , the admin will receive an email alert along with the link to approve it.</li>
