/**************************************
    
    Generic Form Snippet w/ Group Restrictions
    
    This snippet can be used for any form through the PWP.
    If the form is not a site group form, make sure that
    the $defaultFieldCategory variable is set.
    
    The main sections to change will be in SETTINGS and DISPLAY.
    Don't change the CONTENT GENERATION section unless you know
    what you are doing!

    Check the Biogen Idec edit profile page for an example.
