Regarding each ad-category, and ad-listing
1) I'd like to add content above each of my 6 "ad-category" pages, I noticed that there is only a php page used for all ad-listing, is there a way to add a widget or manually add code so I can possibly add descriptions of each category for its own page?
2) One of the category page needs an additional data added to each listing. Currently you get username, date, and category. How can I add a specific additional data to only one ad category? This is crucial for our visitors.
