Can´t find the Main Page

Hi

I have created a few coursers and published them on ITunes U.

Everything works fine, except one thing: when I search for our content I find it but no our site’s root page doesn´t appear!

From the very beginning I saw it, it also appeared on scroll down list to the right.
I created the Welcome Page and you can also click on it I the field Provider when you search for it so it does exists. I wonder how I can make it searchable among the categories to the right and how I make the root page the landing page when I search for the site in ITunes.

Our municipality is called Sigtuna kommun
