i even archive email and msn history to cd loh....
somehow, ppls in power, have this tendency to go back on their
word and made u the scapegoats when the shit hit. Letting them know
that u do such thing made them think twice during their goat
selection.
Not that i actually burn all my past msg or email on to disc....
afterall, i am not the hard working empolyee, else why would i b
posting here during office hrs.... 
I know the feeling. I've had to dig up emails from years ago in
response to "did I say/authorise that?" and "who ask you to do
that?" etc etc
