I'm a current, disillusioned user of vbulletin 3.8.2 looking to switch over to something else. I've been looking at IPB and hearing very good things about the new version. Can you tell me how XenForo stacks up? My forum has about 3,000 members and 172,000 posts, and I HAVE to be able to put ads in the header, in the side bar, and after the first post of each thread. Any thoughts?
