Dynamic home page for logged in and guest user

Hey friends

I want to have a dynamic home page that changes base on user authentication.

I created a page am using as static home page on mysite, but I want a different home page for logged in user, and the home page will be the logged in user friends activity, which will override the default static home page. This will then override the site logo and any other home button to always redirect to logged in friends activity

How can I get this to work.

Please am not good at coding, but I can copy and paste code where it is neccessary if direction is provided to me.
