Web 2.0 tools

I would use Plagiarism Checker for my tool and I would use it for any class in which I would have to write a paper for.  I would use it to make sure I'm not copying anyones work so I dnt get a bad grade. It would help me because I would know its my own work and I wouldn't get in trouble for using other people's work. I think this tool would help me a lot.
