I'd like to duplicate the Search form page, or possibly just create a new tab within the search form page. This new page or tab would be essentially the same as the Search Threads and Posts tab with the only exception being that I would modify the Forums selection field and hard code that input field to only show 5 specific forums that could be selected for searching in.
How would I go about doing this? Maybe create a new template called "search_form_other" and add a tab in the "search_form_tabs" template? Would I have to modify any files?
