Typically I just adjust who is a member of the group by editing the group using vi /etc/group
Editing /etc/group is not recommended. Changes aren't logged and it's easy to make mistakes. It's better to use:
groupadd to create groups gpasswd to add or remove users
(usermod can also add users to a group but gpasswd is safer).
