[KLUG Members] samba directory settings

[bill]

If I wanted a directory on a Samba server that everybody with an account
could read and write to, and they could each read and write to a
subdirectory that any one of them created, I figured I would set it in
smb.conf to 

   writeable = yes
   create mask = 0776

But, I'm not sure exactly how the create mask is operating on the
directory and subdirectories.  Can anybody shed some light on this?

kind regards,
