Display Categories on main Classifieds page

Hi all,

OK so Ive installed the classifieds plugin as I like the integration with buddypress, however Im not keen at all on the main Classifieds page. All it seems to do is randomly list the classifieds, I need some structure.

Can I list the classifieds categories (with or without ad counts)? Is there a shortcode or function I can call to do this?

Thanks
