Hello ,
How can I adjust a site so I have a public page for everyone and some certain pages for certains users groups . It means when a guest comes to my site a public page appears and when a user logged in , a certain section appears respect to usergroup , after the user logged in .

Or can I have a page and determine case in templates so when a user logged in , a block changes relative to the user group ?

Thank you in advance
