I'm unsure on how to go about setting up a log in redirect, like, if a guest visits the site I would like every page to display some kind of message saying you're not logged in and have a button to login/register. right now logged in or not you can visit every page.
I just really don't know how to go about this, I have tried googling but I haven't really found anything that i'm looking for. maybe i'm not searching the right thing?
