=head2 definition ( )

defines wobject properties for Newsletter instances.  You absolutely need 
this method in your new Wobjects.  If you choose to "autoGenerateForms", the
getEditForm method is unnecessary/redundant/useless.

=head2 duplicate ( )

duplicates a Newsletter.  This method is unnecessary, but if you have 
auxiliary, ancillary, or "collateral" data or files related to your 
wobject instances, you will need to duplicate them here.

to be displayed within the page style.

Web facing method which is the default edit page.  This method is entirely
optional.  Take it out unless you specifically want to set a submenu in your
adminConsole views.
