I help a friend to run a website that has never had less than 10,000 unique visitors/day. She averages around 11,000-17,000/day. The website's forums see between 2,000-3,000 unique visitors/day.

The site focuses on a male teen celebrity, with a demographic of what we believe to be chiefly pre-teen/teen girls.

Any suggestions as to how we might want to charge for advertising space? You guys are the experts, after all.
