Are names of groups of users better as singular or plural? [closed]

While there is no industry-wide group naming convention, it helps to stick to a convention that is easy to understand and easy to remember.

Naming groups based on their broad purpose avoids the need to choose between singular and plural names. This way you won't have to reference your list of groups to recall a group's name.

E.g. accounting, hr, shipping, etc...

If the word for the group's purpose demands choosing between singular and plural, e.g. admin or admins, it is best to go with the singular version as it is easier to remember. This method also conforms to Unix group names, e.g. wheel, sudo, audio, etc...
