at the very botom of the pages, where it says Return to Classifieds, and Classifieds Home >>> Auctions,
where do i find that to modify that to read marketplace?
also, how can i make the main title smaller?
That's in classifieds.english.php for anything text that you want to change
The main font size for the big Classifieds word is in a <h1> tag in Gallery.template.php
