I need a little help with Advanced Guestbook

We're using the Advanced Guestbook, and it's working great. I am having a small problem, and hope someone can help me.

How can I create a link from the Guestbook back to our homepage?

Sounds fairly simple, but I haven't a clue where to start and don't want to mess with the files in the forum folder until I know exactly what to do.

Thanks

Go to /templates directory and open header.php
Find a place where you want your link to apear and put this in :
<a href="http://www.your_website_name_here.com/">Text_that_you _want_to_appear_as_a_link_here</a>

Hope that helps, lemme know if you need more help

EDIT:
Make that body.php instead of header.php
Sorry
