I see that we can add Groups to our account which can then be attached to repositories and/or forks and manage access to those repositories all through that screen. The only minor issue with this is that in order to remove a person (say an employee leaves the company) from all projects that s/he is associated with, is to manually go through all our groups and remove that user from each one. Is there any way to say "remove a user from all groups associated with this account?" Or do we have to go through group by group and delete the user?
