If not, does anyone have any recommendations for this? I'm thinking it will be a very simple buy & sell type thing for a site I have coming up. Could possibly use Vanilla forum or similar, but where I'm planning on using C5 for the rest of the site, I'm not sure about integration.
How is this forum integrated / what is it (or is it custom)?
Classifieds - yeah we've got a craigslist type thing in the works if thats what you're talking about.
If you want a way to serve and track ads, check out the ad block in the addons.
So, yes, the Craigslist type thing is what I meant. I've used forums in the past for this purpose as well, but a dedicated Kijiji or Craigslist type thing would be the bees knees.
Having nothing to delete the posts that are expired will be a big problem.
