Something better then adsense for a free forum service?

[thomor25]

I'm not doing too bad with adsense but recently in the past 3 or 4 days my Effective CPM has gone down alot but my visitors are increasing.

So far this month I've had 19,000 uniques, 50,000 visits, 1.5 million page views, and 5.6 million hits.

Is there something else that would pay me more to offset server costs?

Overture contextual?

Don't know the details on that one though.
