Problem: Users in one group need access to files in another.

UNIX allows users to change permissions on their own files.   

  cd (to the directory where your files are)
  ll  (view the files and see what the permissions are:
		if they are -rw-r--r--  then only YOU can write to them,
		if they are -rw-rw-r--  then anyone in your GROUP can write to them,
		if they are -rw-rw-rw-  then ANYONE with access to the system can write to them.)

To change permissions so ANYONE can write to them,
  
  chmod 666 (filename or filenames, wildcards are ok)

To change permissions back so only your group can write to them:

  chmod 664 (...)

=========================
THERE IS A DEFAULT SETTING FOR NEW FILE CREATION in UNIX called umask.  
type "umask" at the command line, if it comes up "022" then files you create
will have "-rw-r--r--" permissions.   To open your files up completely,
change
your umask to 000.
=========================
fwiw, the file permission code is as follows:

	421421421
	rwxrwxrwx   

r=read
w=write
x=executable (do NOT make regular files executable)

the first set of three (rwx) is the owner, second set group and last set
other.

I will be presenting this information in an upcoming UNIX class, some of 
this material may be found at:

There are other tools that have varying success, such as login groups, admin groups
and so on.  Each version of UNIX has some specialized tool to deal with multiple group
membership.  The best solution is to use the man pages, e.g.  "man group"
