I would love to have more input on this, as I am getting ready to launch a site that will have a forum, andthe forum is likely to produce the majority of the pages as well as traffic. It will be associated with a review site, so much of the discussion will be about products and how-to.

Has anyone compared the CTR for logged in users, as compared to those that are not? I know that I heard of people only serving ads to those that are not logged in.

I'm considering several other options for limiting or rotating ads in the forums, such as CPM or some affiliate links, just to reduce the ad-blindness.

As there are several of us involved in this project, would it make sense to designate one of the accounts to be the smart-priced account? That way we could still have ads on the low producing pages, such as fora, and still get paid, though at a lower rate.

My one other consideration is that the forum might just get enough traffic to get an account to premium publisher status. If that is the case, would it be worth putting up with the lower CTR and possible smart-pricing to get enough impressions to get Google's attention?
