Hidden pages are particularly useful as confirmation pages for WOW Forms, which prefer to have a page for the user to land on after entering a form, saying something like "Your form has been emailed.  Thank you for your <whatever...>". However, you may also use a hidden page like any other page.  You just have to arrange links to the hidden page from visible or protected pages.

All of this is explained in a new Application Note entitled: WOW II Pushbutton Website Platform: Using Hidden Pages. A copy of this application note may be downloaded from the documentation page in this dashboard.  While you are there, pick up any other documentation that you have not read in a while.   Click on Documentation to the left.
