group users for new user?

[turtle]

Hello all,

I added on my Xbian system a new user "foobar" and there seems to be no group "users"?

The home directory of the new user looks like this:

drwxr-xr-x 2 foobar foobar 4096 Feb 7 21:37 foobar

Shouldn't this be like this?

drwxr-xr-x 2 foobar users 4096 Feb 7 21:37 foobar

Many thanks in advance

Turtle

PS: By the way, the user "users" is in the system:
> sudo group add users
gives
> groupadd: group 'users' already exists
but users is nowhere to be found in /etc/groups
