Displaying tabs on Customer Portal Home page only after user has signed in

Content

Hi  All

Is this possible ? Basically I want the user to go to the support home page and no other tabs are visible (i.e chat, answers, ask a question, my account) until after the user has signed in.

I can config so it asks them to sign in when they click on either of these tabs but cant figure out out to hide them until after sign on

Thanks!
