I’m sorry but I don’t see how to change those permissions for a category on a discourse instance with “login required” setting in a way to make topics inside it visible to the non registered public.
Could you please elaborate?
As far as I can see any link to any topic on a “login required” discourse instance will always redirect to the login page and never show the topic - is there a way around that?
I guess one could go the opposite way to remove the login required but restrict all other categories read permissions so that only the one / few that should be visible to non registered users are…
But that would also make visible a lot of other stuff to non registered users, like the list of registered users and non-hidden groups and who knows what else… right?
