title: Is it possible to change the username with the Membership API
body: <p>I am using the default sql membership provider with ASP.NET and I would like to provide a page to change the user's username. I believe I am sure I could do this with a custom provider, but can this be done with the default provider?</p>
  
  <p>Second part of my question is:
  Should I allow users to change their username after the account is created?</p>
