I'm PHP challenged and am trying to change the wording of "Back to main index" at the top of the Viper Guestbook page to read "Read more guest notes", which I will then point to a page of old guest notes that we have gathered over the years.

You can get to the guestbook here: horsekeeping.com/guestbook-enter.html

When I "View Source" on my browser I can clearly see where the change is to be made in the text of the page html, but in my directory I cannot find an "index.html" or other file tht contains the words "Back to the main index". Can someone please advise me on where to make this change? Thanks.
