Umm, are you looking to sell the forum, or? ... Just work hard and everything will fall into place. Read all you can, and monetize as smartly as possible. Good luck.
$0.01 per month or $100,000 - it all depends on your niche market and how well you can tackle it and learn it. I would do a few things like turn off your interstitials cause they are the most annoying thing any affiliate has ever created, once i get sent to one i close the site out. But spend time, develop a niche and work towards that and your income revenue can be limit-less Best of luck!
