'Per-Category' anonymous mode

[awesomerobot (Kris)]

You can automatically assign all anonymous users to a group, and then only allow that anonymous group to post in specific categories… does that cover what you’re looking for?

Create a group for anonymous users

Yes, it’s possible. When an anonymous user is created they have an email address in your domain with anon prepended, like this: anon.community.examplesite.com — when creating a group you should be able to add that domain to the automatic membership settings.

edit: oh sorry, I just noticed that I gave you this answer before in another topic - you’re looking for a simpler process for this then?
