title: Granting team read permissions on specific board only
body: <p>I'm trying to create a team that can only see a subset of the boards (e.g. their own area), which is to act as a communication channel between the development teams and other users; meaning, the developers can see/interact with all boards, but the external team can only see/interact with one specific board. But it seems that any team created gets access to the main board no matter what.
  Has anyone attempted this before?</p>
