If you can log into your WP admin panel, find the "Appearance" menu on the left hand (as long as no editing's been done to the admin "look") and find "Editor".

You'll then see a list of templates that can be edited - and your "Friendly Sites" listing is either hardcoded into the main page template or as a sidebar (left-sidebar or sidebar2) or something like that...

That's how I'd do it anyhoo...
