title: Modify Guest Order Email Address
body: <p>I have a guest order in my Magneto system that I need to now modify the email address on file. The customer as mentioned did not create an account so I believe I will need to modify the MySQL tables directly. Can anyone point me in the right direction for what tables I need to modify?</p>
  
  <p>I see an email address in "sales_flat_order", "sales_flat_order_address", and "sales_flat_quote", etc but I am not sure what to edit. Are there any ramifications I need to be aware of when doing this kind of edit?</p>
  
  <p>Thanks!</p>
  
  <p>I am using Magneto Community 1.7.0.2.</p>
