title: How to post on user's wall in facebook after getting permission from user?
body: <p>Is there any good tutorial that teaches how to post on user's wall with API? This is the flow:</p>
  
  <ol>
  <li><p>The user will come on my website and click on post to facebook button at the end of article.</p></li>
  <li><p>He is shown sign in dialog from facebook, after sign in he will give permission to my application to post on his wall on his behalf. </p></li>
  <li><p>After authorization, his shared link will be posted on his wall. </p></li>
  <li><p>Upon future shares, he will not be asked for permissions since he has already given permission to post on his behalf. So in future when he clicks 'Post to Facebook' button under the article then that item will be posted to his wall without opening facebook login dialog. </p></li>
  </ol>
  
  <p>I have searched a lot on tutorials but have not found any that meets my requirement. </p>
  
  <p>I am very new to facebook API and have not worked with it before. </p>
  
  <p>Any suggestions or link to tutorials?
  Thank You!</p>
