Hi Roland, 

There are a number of reasons why that is a bad idea, but I will leave
it to you to research this if you are concerned about the security of
your system.

If you want every account to have access to the directory, there is
already a category of permissions for that - no need to put everyone in
a group. Just make sure the directory has permissions drwxrwxrwx, which
can be done using "chmod 777 directory".

The default permissions when a file or directory is created are
determined by a thing called the umask. Run "umask" to see what it is
set to. 

To set the umask to always create files and directories that are
readable and writable by everyone, set the umask to 000, by running
"umask 000".

If you want this to be the default for a given user, add "umask 000" to
the ".bash_profile" file in the users home directory. If you want this
to be the system default (ie. for all users), edit /etc/bashrc, and
change the umask setting in that file to 000.

Again - there are a number of reasons why this is a bad idea - if you
wish to know about them, just ask, or do some reading on linux security.

Cheers, Ben

You would need to check the permissions of the file they opened, rather
than the directory. They either need to be in the same group as the
file's group and have group write (-----w----) or have "other" write set
(--------w-).

Hope this helps.

Cheers, Ben
