[Mark.B]

I agree about the copyright, it's too intrusive, it's not even worded correctly since, when on that page, it implies the entire site is "Powered by..."

It also messes my footer up which is designed to hold four lines of text, adding a fifth breaks the design.

If copyright is really needed, tiny text in the area of the modification would just about be ok.

But for fairly small additions like this, I'm against copyright notices. It's ok on entirely new features, eg arcades, Paul M's top poster page, etc, or for styles. But if you start adding it to very minor tweak people's sites look a mess.
