Post invisible pages for specific purposes??

Hello,

This is an extremely basic question and the topic title doesn’t make much sense, so here goes. I’ve got a “free stuff” on my site, but I don’t want the link to appear on my main navigation tabs (not a child or a parent of any link) or in my sub navigation tabs.

I only want this page to appear when someone clicks on the Free Resources link that goes to the “free stuff” page. Once in that page you can traverse back to anywhere on the site.

Thanks for read my post! Hope to hear back from you soon!
