It begin to be annoying :-) Adduser enforces a type of system administration where everyone has their own login group and you add people to other groups for permissions. It solves problems with the 1024 character limit / line in /etc/group and makes some sysadmin tasks really easy. Note that you can configure adduser to put the user in other groups, and if you got really annoyed with it you could vi /usr/bin/adduser and fix it. :) adduser is a perl script BTW. > 2) How I can send a mail to all the user of a group ?

Copy the group line into /etc/aliases, put a space after the :, save/quit, and run 'newaliases'.
