@xuelainiao That is tricky, as each individual NodeBB will have separate user databases. You may want to consider adapting the session-sharing plugin so that a cookie is saved on login and read from other the NodeBBs.
But like the others said, Visual Studio Code and Visual Studio 20xx are not the same at all. I'm actually using Visual Studio Code as my general text editor in Linux. Would never do that with any of the Visual Studio 20xx 😉
And yes, Microsoft is horrible at naming their products.
