Hi Joost
Firstly, the <marquee> tag doesn't work on Netscape
If you're doing a complete redesign, you might look into the use of includes, so that you can store the navigation stuff in an external file so that when you add a new section you only have to update the external file and every page will 'inherit' the changes.
I have a guide to doing this on
my site
BTW that isn't a shameless plug for my site, I'm linking to it for information, I genuinely think it may help here
