We have a number of independent groups in our Discourse who shouldn’t have visibility of members in other groups.

I’ve created categories for each group to which only they have access/visibility, which works fine. However, when users post or reply to a topic they can still use @mentions to include any other user in the community.

Is it possible to block this so a user can only @mention other users in their group(s)?

Or turn off @mentions full stop?
