title: Master page and nested forms issue
body: <p>I have got master page with form (runat="server"). However in nested page, I have 2 forms. 
  First is for changing password and second one is for submiting user data... 
  Both must exist, with separate submit buttons.</p>
  
  <p>I tried to enclose appropriate fields with form tags, but I got an error that enclosed forms are not allowed.... How can I achieve my goal?</p>
  
  <p>Thanks!</p>
