Delete my facebook account

You are only able to deactivate your account through Face Book. Go to the lock on your home bar (upper right hand corner), and click on it. There you will see a drop down box. Look for "security" option (if not there, click "see more settings") After clicking "security", the window will show you different security settings. At the bottom you will see "Deactivate Account" in blue font. Click that and you're done after following the prompts.

Whatever you need to delete, whether it is facebook or an ap, can be done in the settings menu on facebook. It is located in a drop down menu on the upper right hand corner of the page.
