I think I said that wrong.  My home page is a K2 "Latest items from (one or more) users or categories" link.  It was including items from a category we didn't want.  So I edited and included all categories except that one.  It worked, as far as the category items not showing, but their RSS icons are still on the front page.  Hope I can attach an image to show you.

 

We are *brand new* to K2, and very ignorant.  We have plenty of Joomla experience, but this is the first K2 site.
