I've replicated the 'search_form_post' template and got the new template all set up. I'm just not sure how to add the tab to the 'search_form_tabs' template. Do I have to modify any files to make this work? Looks like the search posts type changes the URL to "search/?type=post" so if I want to make it "search/?type=classifieds" I imagine I would have to modify a system file. What's the correct way to accomplish what I'm after?
