I would suggest to be careful. I am going to sound like an old person, but I am 19, but whatever. When I was your age I thought the same thing. I thought our campus IT was horrible. There was many times I thought I could just out smart them, over time stuff built up. I ended up getting caught and the lowest punishment they said they could give me was 3 days at an alternative center.
Through this experience I found that the IT guys new what they were doing, the school just didn't want to spend the money.
As for your myspace comment, they aren't stupid for making that app. For one thing your parents would probably realize if they went to go check on you and the App was gone. So I guess you could still close it, but I have found many programs like this keep a log of when they were opened... if you parents no you were on the computer at lets say 7-7:30 and it was closed then... not going to be good.
Just be careful what you do.
I hate myspace and always will. I listened to the 1/17/07 podcast and they talked about a program that could monitor all myspace activity so the parents could see what their kids are doing. I would like to know how are they going to keep the kids from just uninstalling the program. I think that the kids know more than the parents do about computers. I know thats not always true but it is most of the time. I am 16 and know alot more that than the teachers and IT people at my school about computers. I have done the following.
Disabled the monitoring system that can watch your screen and record anything you do on the computers while you are logged in.
Got administrator rights through the add new user wizard in the control panel.
I remote desktop students and teachers which logs them off and when they login it gives them the BSOD
I also got the admin control panel for the monitoring tool they use and was able to control the other computers in the classroom.
I found out how to send messages with novell.
I found out how to get into their main server with ftp, telnet, and ssh
I have done other stuff but am not going to list all of it because it would take days. I am not the only person who figured this stuff out but 2/3 of the school knows how to do this. Its just an example to say that we know what were doing when it comes to computers. It doesnt apply to me because I hate myspace. I know this post is weirdly written and doesnt flow right thats because I am sick and very tired. I am off to bed now and I hope that some people agree with me that us kids know more than you think.
