I started trying some new integration of ads into the forum... not sure I totally like it, there will be some adjustment continuing for sure.
Anyway, the major enhancement I intend to set up in the near future is "revenue sharing", whoever is starts or is participating in a thread (e.g. when responding to a question) would have a % chance to get any adsense advert revenue from that thread.. it would work by simply putting an adsense code into your profile and the site would do the rest. I would put more weight (%) on those replying to an thread.
Anyway, let me know what you think. Perhaps the Big Block (leader-size horizontal rectangle) needs to go...
