XF 2.2 Lock entire forum for new posts but keep threads readable?

[NURV]

Is it possible to lock or close an entire XenForo forum for new posts but keep the existing ones readable? I’m only seeing the option to hide the whole site for maintenance.

I’m considering stopping new posts because I get so few but I want to keep the posts for archive purposes.

Edit the posting permissions for the Registered user group to NEVER.

That’s a great workaround. Thanks!
