Admittedly, the "sticky directory" idea that is in one of the Berkeley systems (i.e. "+t" on directory means you can only unlink files that you own) helps this. I would hope that people on your system aren't malicious enough to do this, but an accidental "rm -f" in the wrong directory can do wonders. Jeff
