Best practice for different user levels on multiple sites - but shared user database

Question

The user database is shared over several q2a instances (A, B, C, D).

Goal:

- User 101 should become administrator of *only* forum A.

- User 102 should become administrator of *only* forum B.

- User 103 should become administrator of forums A, B and C.

As I can see, the central user database qa_users has one field "level" that obviously is valid over all instances.

So what is the best practice to have different levels for each instance?

agree with you. also have you noticed add to favorite is not showing favorites of those particular site.

I think for multiple site sharing single user base, we need to list what all features those are not working.

Favoriting users works for my sites (it's separated by site).
