[PLUG] replacing multipule instances of text

[alex]

WOW! Thanks everyone. Printing this all out as I type. I'm definitely
not a Perlmonger but I'll back up and try anything once. To answer a few

small program to build them and I did hack the CSS page to get the right
color for the background. The pages are nested and here is the link for
anyone that interested to see what I've done.

Thanks again.
