title: Do we really need email confirmation?
body: <p>I've gotten into a habit of using the standard register->send activation email->activate account process for every site that supports user authentication and free registration without  questioning if I really need this.</p>
  
  <p>What are your thoughts on this? If I have captcha on the registration form is the email confirmation process really necessary?</p>
  
  <p>EDIT:</p>
  
  <p>OK, so the general consensus seems to be that by getting the users to confirm the email they entered I'll keep them away from putting someone else's email in there.
  What about when I let users edit their profile/settings and they enter another email?
  If I need to keep them away from entering other people's addresses then I'd need to confirm that email address (by temporarily deactivating their accoun)t every time they change it.</p>
