Is it possible to make a post or page that can only be found by a link?

Example.
I send an email to Bill Jones with a link " www. website .com/newcontact/Bill_Jones"

when Bill gets the email he follows the link to a page that is customized for him.

I don't want the page to show up anywhere in menus ect so that other new contacts do not see a list with their name and 50 other names.

I have tried making "New Contact" category and making the posts private but if you remove "Billl_Jones" from the url in browser then you see all the post listed as names.

In Atahualpa post Options i have checked the "NOT display the Body Title on Single Post or Static Pages" box.

Any ideas?

Thanks Harry

You could use the WordPress 3.0.1 menu systems and not build a menu item for the page.

You could install a plugin that lets you exclude a page from the menu.

You could install a plugin that allows you to set certain pages as private.

For the plugins just go to wordpress.org and start searching.
