I'm having problems with any new content pages I create. I've created a new page but I can't figure out...

1. how to create a link in the menu that goes to that page. At the moment it just sends it straight to the home page, even though I selected the page from the "link to content" option when creating it in the menu

2. how to navigate to a page without it appearing in any menu. I want a page with some special offer text that I can email to a portion of my contacts. I don't want just anybody who visits the site to see it

Thanks for the help
