need more info on the classifieds plugin

Ok, so here we go. The site I am testing the classifieds plugin uses the Twenty Eleven theme and I can’t get any widgets/sidebars to show on the classifieds page. WHY? Is it using its own theming and disrespects the theme’S sidebars? What is going on here? Do I have to create my own template for the classifieds page?

How can I influence what is shown on the default classifieds page? I’m not liking the defaults… i.e. what about if I want to show the price on all classifieds on the classifieds page?
