I would like that too. But specifically add the NodeBB forum inside a wordpress page via template.

EDIT: a plugin similar to that would be a good start -> https://wordpress.org/plugins/wp-discourse/

Is the plugin also able to realtime sync existing user accounts in a wordpress installation?
In contrast, I would also to have the option of not allowing nodeBB installation sign-ups to generate user accounts in my wordpress installation.

That would be awesome!
