Pages Without Navigation in WebSphere Portal

Since my last question was so quickly solved thanks to Kaushal Sinha, I thought I’d try a simpler one. I need to set up a page in WebSphere Portal that doesn’t appear in any of the navigation structure but it does need a known URL. It’s used only as a landing point in the portal, has a portlet that asks a couple of questions and then sends the user on to the right place. It just doesn’t make any sense to navigate to that portal via the links at the top of the standard portal theme, but I can’t just remove permissions from the page because it needs to be available when they come in via external links (where it does make sense).

I’m sure it’s simple, but I haven’t found anything in the portal manual…
