Which forum software has ads integrated

Which forum software (phpBB, vBulletin, simplemachines) has supports having ads without custom programming?  And if none, how difficult is it to custom program this feature?

I think there is no forum software that do this automatically.

What kind of advertising you want to integrate to your forum?

Like AdSense.  I found that SimpleMachines has a mod that I can install on their forums that will do that.

yes I think these mods are for all bigger forum scripts

If you want to put adsense on your forum, you don't really need a modification. You just have to put the ad code in your templates.

For instance in SMF you just need to add the code in the index.template.php file.

You could go down the drupal route, simply activate the forum module and download the adsense module and activate no programming what so ever. However the adds would have limited locations as they would only be able to be produced in the block regions however adding new regions is 1 line of code. for more info http://www.drupal.org

I see Tim, you like Drupal ;)

that's great I will try Drupal next time (this way I have someone I can ask here)

We use it alot but I also like Joomla and moodle, even plone has its uses but for most site development we work with drupal, easy to train staff, easy to develop for easy to train clients on but still lets you get under the hood to tinker ;)
