You are really missing the point.
Whats to keep me from downloading your page that says "design by ace dogg" and changing it to say "design by evil-empire in cooperation with Janet reno"? Hmmmmm?
What I'm saying is that copyright statements on web pages mean NOTHING. I mean, keep putting them on your pages, it does help (a little), but it doesn't stop anyone really. Only people who can hire lawyers and such can really back copyright statements up.
The only medium on the web (thats used widely) that can be protected and proven that it is yours are images. Not only can you save images in their original format (.psd for me, before I export to .gif), but you can also add virtually undectable digimarcs (that name pops into my head, I don't if its really called that). To add those, you simply have to register at the company's website, and add that little bit to all your images. It's extremly hard to cover up or hide that mark, and it can survive multiple scannings/printings (or so I've heard).
But web pages? You don't have much of a chance. I mean, seriously, in about 5 minutes I could have a replica of this thread installed on my server, along with all the images (thats including upload time on a 56k modem!). CGI scripts are a little more difficult, but it would probably be easy enough to steal one. Stealing is easy.
