title: Remove user from group A if they are a member of group B
body: <p>I have two groups; group A and group B. If a user is part of group B, then I want to remove them from group A. This is because the groups are mutually exclusive. </p>
  
  <p>I have found some scripts that will remove the user from a group, but not on the condition of the user being part of another group.</p>
  
  <p>Can someone help?</p>
