Copyrights, etc.

Hey guys,

I got a quickie. I first off attend a University here in Indiana and developed a webpage on there server, no big deal. Recently I found out that this guy from the same university who happens to be a senior (I'm a sophomore if that matters) stole ALL my work on my webpage! The whole design and implementation was developed BY me... on some parts there are word for word things I wrote! The layouts are the exact same, minor changes such as replacing my name with his. Oh, apparently a stupid thing he left was my volunteer work on the webpage which in the source code has my name. I did have a copyright on the bottom of the website for 2003... I don't know if that protects me from anything. My professor has seen this was my design.

Does anyone have advice on this or maybe previous experience? I already emailed all the guys in the Computer Center to see what they say. But to me this is plagiarism and is a serious act! What do you guys think??

Thanks a lot for reading this and your input is greatly appreciated!
PS: Sorry if it's wordy... and not make sense-ish :)
