Creating a closed category open for comments?

[justwordme]

I would like to create a Category of featured product(s) of the month. I don't want anyone else to be able to post products/create new threads. But I want people to be able to comment on said products/threads. How do I do this???

Revoke the Post new thread permission for the Registered user group in the node.

Then Allow it for the user group or users who are allowed to post new threads.
