You allow _all_ users to write to this directory. It would be better to put
them all in one group and then do a chmod g+rw for this dir. But this will
still allow people to delete other peoples files (because deleting means
changing the folder, not the file). If you don't want people to do this,
you need to set the sticky bit. Then you would get chmod g+rwt.
Hope this helps
