plagerism

What can i say about plagerism i probally spelled that one first off, but it is toatolly wrong. I understand that it is okay to use someone elses information on certain subjects as long as your show your refrence where you got it from. It is against law.... I once wrote a term paper on child abuse for school and i found out that one of my class mates stole my paper copy it and must have thrown it out or something. I was issued an f and then the teacher as her to read her paper in front of the class which she didn't want to do but did ne way and i spoke up and was like thats my paper and luckily i kept the rough draft and she got suspended from school and i think some authorit was involved too. When your doing this online though its hard sometimes not to use someone else words but if you reword it in your own i think you would be fine right .... take it easy until next time peeps.....
