I've already checked out this doc, but "Clicking on Roles within Admin will show the current list of roles" - is a worthless enigmatic advice. Where to find this "Roles" link???
I said it's wortless because it's not precise at all.
"Click Role" says anything to you? Well, probably yes, but as I assume, you know ezPublish well. I do not, so I need clear, precise hints.
When I log in to admin panel, I see no "Role" link. The only thing that this advice told me, is what I have known well before reading it: Give anonymous user right to view new classes.
