[cobalt-users] Who is ruining my beloved boss?

["Blabla" <blabla@xxxxxxxxxxxxxxxxxxx>]

Hi,

someone in my company does VERY huge downloads. That´s no more fun...

Where/how can I get informations which user´s doing so?
(No, he will not lose his job. I just want to beat him a little bit. %~P )

Bye, Jörg
