If we would work around this history, making it just "more probable" to show up, we would run in a new bunch of problems, such as showing weighted banners too often. The only weighting we have been playing with for a while, was the favouring of new banners until they have somewhat levelled compared to the old banners, but even this method was then abbandoned.

Not sure if it needs to be too complex, just basing the ad placement on probabilities. If one's site carries enough traffic and it has a decent "randomiser" the probabilities should work out in the end.

I use Advertisment Management on my phpBB site (which is being migrated to vBulletin, hence the "need") and it works pretty well.

PS, the missing banner seemed to be a problem with the vbulletin ad side - just deleted the ad and created a new one.
