I have Problems with Logme

Hi Guys

I am working in software firm, I have few questions which i need your help very badly.My network admin installed Logme software to monitor my terminal.

1) How can i disable Logme settings at my terminal ?
2) Last night i tried to switch off my computer i got message that my computer is being used by another user , How can i come to know if my terminal is using by another user.?
3) Will i get any pop up screen if any one uses my terminal remotely, if so, where i can see the message.?

I appreciate if you guys can sort out my problem ,
