This was in the UBB.Classic version of the message board and was dropped in Threads. This has been requested a few times to have placed back on the product.

I wrote a mod for this in UBB.Classic many years ago. I have changed this to s stand alone software pulling the rotating banner Ads into the board under an iFrame with a login for the banner owner to see his / her banner stats for views and clicks with an automated tracking system as well as built in billing for payment.

Requested a few times in the past to relieve server stress in the database for very large forums. Has been mentioned that this may / will be an addition in the version 8 of Threads sometime in the release or future.
