title: Remove users with Duplicate Email in ASP.NET membership provider
body: <p>I'm looking for the most efficient way to remove users with duplicate emails in my asp.net MVC2 website that is using the default membership provider.</p>
  
  <p>We launched this site and did not set unique emails to true, now that I am trying to implement a Forgot Username/Password feature I've come to realize over 100 users have re-registered as they forgot their password and there was no forgot password feature.  This is a problem as I need to have the user enter their email to send them their username and password reset email.  This fails since multiple users share an email.
  I wish I had noticed the unique email option in the web.config before launch, would have saved a huge hassle. :(</p>
  
  <p>I would like to delete all these accounts easily without having to do it manually 1 by 1, and I will then contact them and let them know their duplicate account has been created.</p>
  
  <p>Whats the best way to go about doing this?  Some users have registered with the same email up to 5 times.</p>
