[SOLVED] Private Page Link Yields "Not Found" result

Using Atahualpa 3.4.2 and WordPress 2.8.2, I wanted to create a landing page for visitors to my blog from Twitter.

I don't want the page to be a visible page that will register on my top menu or pages sidebar widget.
My solution was to create a 'private' page. The problem I have is that when I am not logged in as an administrator the link to that page (http://www.beautyprpro.com/welcome-t...-from-twitter/) results in a NOT Found message.

How else might I solve this problem of needing a landing page? Any help appreciated.

Thanks
