In an earlier tutorial, I explained how your frontpage content item will disappear if you don't have the default 'Home' link at the top of your Main Menu.  But, what if you don't want your 'Welcome to the website' content item on the Frontpage, but you would rather have Sobi or CMS Realty to display instead?  Believe it or not, I didn't at first realize how to do this (but should have).
