Vbulletin 4 and ads specific to certain subforums?
 

I run a site at www.lawstudents.ca. Forums are currently phpbb* and I use openx to serve google adsense mixed with direct sale ads.

Typically* people will buy a banner advertisment and have their ads show forum wide. This has been fine for the most part* except now some advertisers want to buy ad space only in certain subforums. One example would be that we have a buy/sell subforum* and an advertiser wants their ads to only show there and never anywhere else. Right now* I have ads being served from overall_header.html (not sure if vbulletin has an equivalent) and it doesnt seem like i can restrict based on subforums. That is* the ad invocation code is put into a static element that appears everywhere* not just in specific subforums. Openx sees the forums as one page.

Does anyone know if vbulletin 3.8 or 4 has any built in ad functionality* and would work with openx to enable this sort of specific banner requirement? We are considering moving to vbulletin* and this will be a huge feature if it is possible.

Thanks.
