I'm on ICQ only when I NEED to be, I hate those stupid thing's, people always poking into you're computer when you're busy

, and you don't want to be a ***** but you can't talk, or the reverse hapens and you end up with fifteen open windows to people that arn't responding,
my sister on the other hand loves the damn things, and chat rooms too, but she's an idiot and gona end up kidnaped and on some kiddy porn site

, we've grounder her, hell I put a damn pad lock on the computer, she just unpluged the keyboard and mouse and pluged in the ones from her room, well I riped the plug out of that, she found another one, I cut the end of the plug off of that one, she sneaks down and fishes the mouse out from behind, I can tell she's been on becase she always erases the history of were she's been but leaves the history window open

, not that that stops me from finding out were she's been, but there are fifty billion chat servers and I have to ban her from them one by one,
is there a way to totaly disable chat rooms, and IM software too?
