I guess I'm missing something here. Classified listings are for someone selling something, wanting to buy or trade something or for offering a service or giving something away. B/S/T is for buying, selling, trading, giving away (PIF) and the vendor area adds services. So whats the difference. If the "new classifieds" meet the needs of the board change it over and be done with it. If they don't then leave it as is. Some people don't like change but if its for the best of the majority the go for it.
Just please don't let them have the colors of the linked site
