Dolphin home page - Require Log-In

Can any one tell me how I can hide my home page contents until the user has logged into his/her account?

Thank

Close to the same thing you did to the main menu.

Go to Builders => Page Builders and turn off all the guest items by removing the checkmark from the box for guests and leave it there for members.  Keep in mind, no one will see any of it unless they are logged in, including the google bots if you turn off the content. 

Your other option is to create a splash page, name it html and require a log in with it.
