title: ASP.NET MVC - GET with one ViewModel, POST with another
body: <p>I'm kind of a noob so please forgive me if this is a dumb question.</p>
  
  <p>I am loading a page successfully using Model Binding in ASP.NET MVC 2.  Now I want to use Model Binding to submit the results of a form, but I want to use a different Model that the one I loaded with.  Is this possible?  Or should I just use the same ViewModel for both purposes?</p>
