You have no traffic. Before you worry about monetizing anything you have to have something to monetize. YPN converts poorly on sites optimized for YPN. Forums typically perform very poorly with contextual advertising. You need TONS of traffic. You're Forums looks fine - I just glanced at it. Get your traffic. Then provide products and services that are on Target with your Audience. YPN even if you could get in right now isn't going to make you any money. You would likely be tossed for low or zero conversions. Yahoo is a business. They are going to look at your site and see if it can make them money RIGHT NOW. And it can't. Potential is for speculators.
