That's just plain illegal, and I want you to change it. That is technically feasible, but I don't think it's a good solution. Make it configurable, though. In my opinion, unless you've got a specific reason to remove it or change it, then you should leave it alone. I'll agree with Tasos on one thing.
Talk is very cheap.
And a little knowledge is dangerous, especially when a lot of knowledge is necessary. And with that, I'll go crawl back into the woodwork, since I don't believe in talking to brick walls. But if Tasos had any knowledge of copyright, he wouldn't be saying what he was saying. I just hope he doesn't learn the hard way. But that's not what will happen.
