I'm trying to build a classifieds site, was curious what's recommended for building a quality classifieds site? Is Vbulletin a good fit for this? It seems article directory software (or related) may work with these posts too, but I'm not sure.. It at lease seems to me article directory builder software would work too, as it allows users to post material, but let me know if I'm wrong in this assessment. The classified site of course would need to be able to rename titles and fields to "used red widget for sale.." for example What is probably the best paid version and in case it's out of my budget, what's decent and free (or cheap) software? Are forums or directories the best software tools for this?
Wordpress is also good for this. You might also take interest in trying out Pligg as it's very oriented to the type of service that you're looking for.
We started out as an article directory and as it took off quite well we added forum and now a classifieds site as well. For classified site I would recommend 68 classifieds.
Most big players in classified ads industry have custom made softwares. I dont think vbulletin would get you all the flexibility you need to run a successful classified ads site.
