content management recommendations

Hi.

So far none of these fits the requirements.

I need one that:
1. A user doesn't have to log in.
2. A php script.

Say for example I have 5 sections on my site.

Right now I'm able to place a tag on each indivdual page that calls up my banner program. It is a nightmare having to change something on each indivdual page. Also it takes for ever if I need to update my links on the left side of the page.

Say one section is call motorsports.

Okay. With the CMS program I would like to put a tag on top of the template to target that section. 5 individual tags for the different sections. motorsports, flying, scuba diving etc.....

With postnuke it looks like I would have to integrate it with vbulletin. I am stuck at 2.2.8 because I have some major modifications to the script. So I need a CMS that is indepensent of the vbulletin script. Nothing that fancy. Just something that will save me some work whenever I need to make a modification to a link.
What do you think?

Thanks.
