Use https://github.com/NodeBB/nodebb-plugin-category-optin but beware if you have thousands of categories and millions of users this plugin will create a lot of entries in the database.
remove new topic option
i have hosted nodebb on my private server and i want remove new topic from user
i want user to post inside of given categories only and user should not be able to add any new topic
only admin can add use
can we do something like this ?
If you only want people to be able to reply to existing topics, then you can disable the permission of registered users to create new topics in the ACP privileges page. Make sure you apply it to every category.
ACP page ?
The admin control panel.
Thanks found that
