Someone doesn't know about Grooveshark.com.
Well, I've never really wanted to listen to music myself at school, and if I did, I certainly wouldn't use a school-computer.
I could do so now if I wanted to at College, as they allow you access to YouTube and such.
But they this unusual tool-thing where the computer will stop you from getting onto YouTube, bring you to a page where it tells you that you have 30 minutes of allocatted time on YouTube, and then let you choose to continue to your page and start using your time.
And once you reach 30 minutes you would have to log out of your account and sign back in and restart.
I'm not quite sure what the purpose of it is, since they let us use YouTube in the first place.
I think it's possibly to just try and make sure we don't spend all our time on YouTube and actually use the computers for college work so that we don't take up a computer and prevent someone else from actually doing something proper.
