Professional Question - Dealing with MANY ppl on one site

Good morning,

I am about 90% completed with a site that I designed for a local
chamber.  Totally went low on my price as a community service.  So far
all the ppl that are "in charge" have said "how great" the site is.  

Today I received an e-mail from ONE member who is using Netscape 4 and
is complaining that the "unlinked" pages in the navigation are Black,
therefore they are hard to see.  He is also complaining that with his
machine the email will not work from within Netscape 4.

These are the stats:
Netscape 5.91%  -  MSIE 91.13%  -  Other 2.95%

Question:
1) Would you for the relatively small % redo the unlinked pages to make
sure they are "white" in Netscape 4.
2) Since I am using style sheet link and css in header what would be the
fastest way to "update" all these "black" unlinked pages?
3) What do you think the problem is with his e-mail? (I tried it on my
Netscape 6 box and it worked just fine)
4) Would you restrain yourself from telling this one person to go jump
in a lake?

The site is 
http://www.remerchamberofcommerce.com

Any comments/suggestions would be most appreciated.

I finally got it all together...
I just wish I could remember where I set it down.
